2y(y-3)-(y-3)=0

Solution for 2y(y-3)-(y-3)=0 equation:

Simplifying
2y(y + -3) + -1(y + -3) = 0

Reorder the terms:
2y(-3 + y) + -1(y + -3) = 0
(-3 * 2y + y * 2y) + -1(y + -3) = 0
(-6y + 2y2) + -1(y + -3) = 0

Reorder the terms:
-6y + 2y2 + -1(-3 + y) = 0
-6y + 2y2 + (-3 * -1 + y * -1) = 0
-6y + 2y2 + (3 + -1y) = 0

Reorder the terms:
3 + -6y + -1y + 2y2 = 0

Combine like terms: -6y + -1y = -7y
