Solving Quadratic Equations by Factoring Solving Quadratic Equations by Factoring
Solve for x in 3x^2 + 8x + 4 = 0
3x^2 + 8x + 4 = 0 (3x + 2)(x+2)= 0
3x + 2 = 0 of x + 2= 0
x= -2/3 or x= -2
Solve for x in x= +/- 2
x^2 + 4 = 0

Solve the following equations for x and y 3x + 2y = 5
7x - y =1
3x +2y =5 3x + 2y = 5
7x - y = 1 2(7x - y =1)
3x + 2y = 5
14x -2y= 2
17x= 7
x= 7/17
Plug in for x
3(7/17) + 2y = 5
21/17 + 2y = 5
2y = 5 - 21/17
2y= 78/17
y= 39/17
