What is the elimination method in solving systems of equations?
It's a technique where equations are added or subtracted to remove one variable, making the system easier to solve.
x + y = 8
x - y = 2
x = 5
y = 3
x^2 + 6x = 9
(x+3)(x+3) or (x + 3)^2
x^2 = 16
x = +4

How does substitution work for solving systems of equations?
You solve one equation for a variable and replace it in the other equation to find the solution.
2x + y = 10
x - y = 1
x = 11/3
y = 8/3
x^2 - 4
(x - 2)(x + 2)
y^2 = 25
y = 5

What does factoring mean in solving equations?
It involves expressing a polynomial as the product of its factors to simplify solving, often setting factors to zero.
x - 3y = 7
2x + y = 10
x = 37/7
y =10
2x^2 + 7x + 3
(2x + 3)(x + 1)
4x^2 = 36
x = +3

How is the square root property used in quadratic equations?
You isolate the squared term and take the square root of both sides to solve for the variable.
3x - y = 12
x - y = 3
x = 15/4
y = 3/4
3x*2 + 5x - 2
(3x - 1)(x + 2)
9x^2 = 81
x = +3

What does quadratic mean?
A degree-two polynomial equation, written ax2+bx+c=0ax^2 + bx + c = 0ax2+bx+c=0, involving squared terms, forming parabolic graphs.
6x + 4y = 16
5x - 2y = 9
x = 2
y = 1
6x^2 - 11x + 4
(2x + 1)(3x - 4)
5a^2 = 45
a = +3
