This document discusses solving the absolute value equation |2x + 3| = 9. To solve this equation, we first break it into cases: when 2x + 3 is greater than or equal to 0, and when it is less than 0. We then solve each case separately and combine the solutions.
Linear Equations - Counting Solutions
Factorise 12, and think about what integer values the terms on the Left Hand Side can take that satisfy the equation.
Quadratic Equations - Counting Solutions
This document discusses solving the quadratic equation x2 – 7 |x| – 18 = 0. It splits the problem into two cases: when x is greater than 0 and when x is less than 0. For each case, it is shown that the only real solution is x = 9. Therefore, the number of real solutions to the given equation is 2, as indicated by choice (a).

This document appears to be discussing an algebraic expression involving an absolute value term. However, there is not enough context or information provided to generate a meaningful 3 sentence summary. The document is a single line that does not convey the essential information or high level topic being discussed.
Quadratic Equations - Playing with the Discriminant
The document discusses solving a quadratic equation with integer roots. For the equation x^2 - 11x + |p| = 0 to have integer roots, the discriminant must be a perfect square. The discriminant is calculated to be 121 - 4|p|. For the discriminant to be a perfect square, |p| can take the values 0, 10, 18, 24, 28, 30. Therefore, the number of integer values p can take is greater than 8.
Algebra 1 common factor
The document provides an algebra lesson on factorizing expressions using common factors. It includes examples of expanding and factorizing expressions such as 2(x + 6), ax - bx, and 3x + 18. Students are instructed to complete a factorisation worksheet from an online source to practice these skills. The summary is in 3 sentences.
Equation
1) This document discusses how to solve linear equations by manipulating the equations to isolate the variable.
2) Key steps shown include subtracting or adding the same quantity to both sides of the equation and then dividing both sides by the coefficient of the variable.
3) Several examples are provided of solving equations for x by applying operations to both sides such as adding or subtracting numbers, multiplying both sides by constants, and then simplifying.
Numeros reales Marialy Castillo
The document defines mathematical concepts such as sets, elements, absolute value, and inequalities. It provides examples of sets like the colors of the rainbow and prime numbers. It also explains how to solve absolute value equations and inequalities, such as finding the values of X that satisfy the equation |X - 5| = 4. Finally, it discusses how real numbers can be defined by periodic or non-periodic decimal expansions.

Veidic methods of squaring
This document provides a simple method for squaring numbers between 12 and 19. It works by breaking the number into its tens and ones place values, squaring them separately, and then recombining the results.
