This document provides instructions for solving quadratic equations by completing the square. It explains that you can complete the square by adding a constant to both sides of the equation to make the quadratic term a perfect square. You then take the square root of both sides to solve for x. It also notes that when the leading coefficient is not 1, you must first divide both sides by the coefficient a. Finally, it shows that completing the square allows you to derive the quadratic formula, which can be used to solve any quadratic equation in standard form.

Finally, it discusses different methods for solving systems of linear equations, including substitution and elimination.
linear equation in 2 variables
1) A linear equation in two variables can be written in the form ax + by + c = 0, where a, b, and c are real numbers and a and b are not equal to 0.
2) The solution to a linear equation is the ordered pair that satisfies the equation when substituted into it.
3) Linear equations can be graphed on a Cartesian plane by plotting the solutions as points and connecting them.
