(x+5)(x-1)=

Solution for (x+5)(x-1)= equation:

Simplifying
(x + 5)(x + -1) = 0

Reorder the terms:
(5 + x)(x + -1) = 0

Reorder the terms:
(5 + x)(-1 + x) = 0

Multiply (5 + x) * (-1 + x)
(5(-1 + x) + x(-1 + x)) = 0
((-1 * 5 + x * 5) + x(-1 + x)) = 0
((-5 + 5x) + x(-1 + x)) = 0
(-5 + 5x + (-1 * x + x * x)) = 0
(-5 + 5x + (-1x + x2)) = 0

Combine like terms: 5x + -1x = 4x
(-5 + 4x + x2) = 0

Solving
-5 + 4x + x2 = 0

Solving for variable 'x'.

Factor a trinomial.
