Factors on difference of two squares
The lesson plan is for a math class on factoring the difference of two squares. It outlines learning objectives, content, materials, and activities. The objectives are for students to factor differences of squares, find square roots, and understand real-world applications. Content includes the skill of factoring expressions and finding square roots. Students will do an activity investigating patterns in products of differences of squares and generalize the relationship. They will learn that to factor such expressions, the factors are the sum and difference of the square roots of the terms. An evaluation and assignment reinforce these skills.
Rational Exponents
Rational exponents allow radicals to be written as fractional exponents. To write a radical with an index of n as a rational exponent, the index becomes the denominator and the exponent of the radicand becomes the numerator. The rules of exponents still apply to rational exponents. Expressions with rational exponents are simplified by having no negative exponents, no fractional exponents in the denominator, not being a complex fraction, and having the least possible index for any remaining radicals. Examples show how to evaluate, simplify, and perform operations on expressions with rational exponents.

The document also covers rationalizing denominators, solving radical equations, and using the Pythagorean theorem and distance formula.
Multiplying polynomials
The document describes three methods for multiplying polynomials:
1) The distributive property, which involves multiplying each term of one polynomial with each term of the other.
2) FOIL (First, Outer, Inner, Last), which is a mnemonic for multiplying binomials by multiplying corresponding terms.
3) The box method, which involves drawing a box and writing one polynomial above and beside the box, then multiplying corresponding terms. Examples are provided to demonstrate each method.

It provides examples of factoring expressions like x^2 + 8x + 16 into (x + 4)^2. For an expression to be a perfect square trinomial, the first term must be a perfect square, the third term must be a perfect square, and the middle term must be twice the product of the square roots of the first and last terms. Students are provided examples and exercises to practice factoring various square trinomial expressions.
Multiplication of radicals
This document discusses the three cases of multiplying radicals:
1) Same indices - the indices are multiplied but the radicands are multiplied, e.g. 3√4 * 4√4 = 12√4
2) Different indices but same radicand - the indices are added but the radicand is multiplied, e.g. 5√2 * 5√3 = 5√6
3) Totally different indices and radicands - the indices and radicands are multiplied separately, e.g. 4√3 * 5√2 = 20√6

Add / Sub
Yes, adding or subtracting the same number from each entry in a magic square will preserve the magic property, where all rows, columns and diagonals sum to the same number. This is because adding or subtracting a constant to each term in a sum does not change the total. So the underlying structure and relationships that make the square "magic" are maintained regardless of what constant is added or subtracted from each entry.
Adding and subtracting integers
The document defines integers and provides rules for adding and subtracting integers:
- Integers include all positive whole numbers and their opposites, including zero.
- For addition, if signs are the same, add the numbers and keep the sign; if different, subtract the smaller number from the larger and keep the sign of the number with the larger absolute value.
- For subtraction, change a negative number to its positive equivalent by changing the sign, then add. This allows subtraction to follow the same rules as addition.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
