Solution for -(3x+3)(2x+4)=0 equation:


Simplifying
-1(3x + 3)(2x + 4) = 0

Reorder the terms:
-1(3 + 3x)(2x + 4) = 0

Reorder the terms:
-1(3 + 3x)(4 + 2x) = 0

Multiply (3 + 3x) * (4 + 2x)
-1(3(4 + 2x) + 3x * (4 + 2x)) = 0
-1((4 * 3 + 2x * 3) + 3x * (4 + 2x)) = 0
-1((12 + 6x) + 3x * (4 + 2x)) = 0
-1(12 + 6x + (4 * 3x + 2x * 3x)) = 0
-1(12 + 6x + (12x + 6x2)) = 0

Combine like terms: 6x + 12x = 18x
-1(12 + 18x + 6x2) = 0
(12 * -1 + 18x * -1 + 6x2 * -1) = 0
(-12 + -18x + -6x2) = 0
