Question and answer
Factor each problem completely. Solve for x: X^2 – 12 = -4x. Please show the steps on how you got your answer. Thanks!
x^2 – 12 = -4x x^2 -12 + 4x = 0 x^2 + 6x -2x -12 = 0 ( x + 6) ( x - 2) = 0

x^2 – 12 = -4x
x^2 -12 + 4x = 0
x^2 + 6x -2x -12 = 0
( x + 6) ( x - 2) = 0

(12y³ + 8y² + 20y) / (2y)
= (12y³/2y) + (8y²/2y) + (20y/2y)
= 6y^2 + 4y + 10

(5x – 3.6) – (4x + 1.2)

= 5x - 3.6 - 4x - 1.2

= 5x - 4x - 3.6 - 1.2

= x - 4.8

(6x^2 - 25x - 10) / (3x + 2)
= (6x^2/3x+2) - (25x/3x+2) - (10/3x+2)
= 2x - 29/3 R. 28/3
