3x^2+12x+12 solve or factor the equation

x = - 2 (multiplicity 2).

Step-by-step explanation:

3x^2+12x+12 = 0

3 (x^2 + 4x + 4) = 0

3 (x + 2) (x + 2) = 0

x = - 2 (multiplicity 2).

2 roots - both equal.

3 (x+2) (x+2)

Step-by-step explanation:

Given 3x²+12x+12

We expand the equation

That is,

3x²+6x+6x+12

We add parentheses to factor out

(3x²+6x) + (6x+12)

3x (x+2) + 6 (x+2) > Taking out the

common factors.

(3x+6) (x+2)

= 3 (x+2) (x+2)
