Question

Factor the polynomial:
x + 4x + 4 = 0

Answer 1

x+4x+4=0

Combine x and 4x to get 5x.

5x+4=0

Subtract 4 from both sides. Anything subtracted from zero gives its negation.

5x=−4

Divide both sides by 5.

5x/5 = -4/5

x = -4/5

Explanation:

Answer 2

Add similar elements: x+4x=5x
5x+4=0
Subtract 4 from both sides
5x+4-4=0-4
Simplify
5x=-4
Divide both sides by 5
5x/5 = -4/5
Simplify
X= -4/5
