(x+4)(x-1)=6

Solution for (x+4)(x-1)=6 equation:

Simplifying
(x + 4)(x + -1) = 6

Reorder the terms:
(4 + x)(x + -1) = 6

Reorder the terms:
(4 + x)(-1 + x) = 6

Multiply (4 + x) * (-1 + x)
(4(-1 + x) + x(-1 + x)) = 6
((-1 * 4 + x * 4) + x(-1 + x)) = 6
((-4 + 4x) + x(-1 + x)) = 6
(-4 + 4x + (-1 * x + x * x)) = 6
(-4 + 4x + (-1x + x2)) = 6

Combine like terms: 4x + -1x = 3x
(-4 + 3x + x2) = 6

Solving
-4 + 3x + x2 = 6
