3(x+5)(x-6)=y

Solution for 3(x+5)(x-6)=y equation:

Simplifying
3(x + 5)(x + -6) = y

Reorder the terms:
3(5 + x)(x + -6) = y

Reorder the terms:
3(5 + x)(-6 + x) = y

Multiply (5 + x) * (-6 + x)
3(5(-6 + x) + x(-6 + x)) = y
3((-6 * 5 + x * 5) + x(-6 + x)) = y
3((-30 + 5x) + x(-6 + x)) = y
3(-30 + 5x + (-6 * x + x * x)) = y
3(-30 + 5x + (-6x + x2)) = y

Combine like terms: 5x + -6x = -1x
3(-30 + -1x + x2) = y
(-30 * 3 + -1x * 3 + x2 * 3) = y
(-90 + -3x + 3x2) = y

Solving
-90 + -3x + 3x2 = y

Solving for variable 'x'.

Combine like terms: y + -1y = 0
-90 + -3x + 3x2 + -1y = 0
