Solution for 3y(2y-4)-6y(4y+4)= equation:


Simplifying
3y(2y + -4) + -6y(4y + 4) = 0

Reorder the terms:
3y(-4 + 2y) + -6y(4y + 4) = 0
(-4 * 3y + 2y * 3y) + -6y(4y + 4) = 0
(-12y + 6y2) + -6y(4y + 4) = 0

Reorder the terms:
-12y + 6y2 + -6y(4 + 4y) = 0
-12y + 6y2 + (4 * -6y + 4y * -6y) = 0
-12y + 6y2 + (-24y + -24y2) = 0

Reorder the terms:
-12y + -24y + 6y2 + -24y2 = 0

Combine like terms: -12y + -24y = -36y
-36y + 6y2 + -24y2 = 0
