Nikhil number pattern formulas
There are several common number patterns that follow specific rules. Square number sequences follow the rule of n^2, where the nth term is the square of n. Arithmetic sequences follow repetitive addition, where each term is created by adding a fixed number to the previous term. Geometric sequences follow repetitive multiplication, where each term is created by multiplying the previous term by a fixed number. The Fibonacci sequence is where each term is the sum of the two terms before it, starting with 1, 1. These patterns can be represented by general formulas to calculate any term in the sequence.

* The initial height (c) is still 2 feet
* The initial velocity (v) is now 20 feet/second
* The target height (h) is still 20 feet
So the equation is:
20 = -16t^2 + 20t + 2
0 = -16t^2 + 20t + 18 (subtract 20 from both sides)
Evaluating the discriminant:
(20)^2 - 4(-16)(-18) = 400 - 288 = 112
Since the discriminant is positive
6.4 factoring and solving polynomial equations

MIT Math Syllabus 10-3 Lesson 7: Quadratic equations
This document discusses different methods for solving quadratic equations:
1) Factoring - Setting each factor of the factored quadratic equation equal to zero and solving.
2) Taking square roots - Taking the square root of both sides to isolate the variable.
3) Completing the square - Adding terms to complete the quadratic into a perfect square trinomial form.
4) Quadratic formula - A general formula for solving any quadratic equation using the coefficients.
The discriminant (b^2 - 4ac) determines the nature of the solutions, with positive discriminant yielding two real solutions and negative or zero discriminant yielding non-real or repeated solutions.
