2(x+1)(x-4)=y

Solution for 2(x+1)(x-4)=y equation:

Simplifying
2(x + 1)(x + -4) = y

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

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

Multiply (1 + x) * (-4 + x)
2(1(-4 + x) + x(-4 + x)) = y
2((-4 * 1 + x * 1) + x(-4 + x)) = y
2((-4 + 1x) + x(-4 + x)) = y
2(-4 + 1x + (-4 * x + x * x)) = y
2(-4 + 1x + (-4x + x2)) = y

Combine like terms: 1x + -4x = -3x
2(-4 + -3x + x2) = y
(-4 * 2 + -3x * 2 + x2 * 2) = y
(-8 + -6x + 2x2) = y

Solving
-8 + -6x + 2x2 = y

Solving for variable 'x'.

Combine like terms: y + -1y = 0
-8 + -6x + 2x2 + -1y = 0
