(x+13)(x-1)=

Solution for (x+13)(x-1)= equation:

Simplifying
(x + 13)(x + -1) = 0

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

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

Multiply (13 + x) * (-1 + x)
(13(-1 + x) + x(-1 + x)) = 0
((-1 * 13 + x * 13) + x(-1 + x)) = 0
((-13 + 13x) + x(-1 + x)) = 0
(-13 + 13x + (-1 * x + x * x)) = 0
(-13 + 13x + (-1x + x2)) = 0

Combine like terms: 13x + -1x = 12x
(-13 + 12x + x2) = 0

Solving
-13 + 12x + x2 = 0

Solving for variable 'x'.

-1x = 13

Divide each side by '-1'.
x = -13

Simplifying
x = -13
Subproblem 2
Set the factor '(1 + -1x)' equal to zero and attempt to solve:

Simplifying
1 + -1x = 0

Solving
1 + -1x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -1x = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1x = 0 + -1
-1x = 0 + -1

Combine like terms: 0 + -1 = -1
-1x = -1

Divide each side by '-1'.
x = 1

Simplifying
x = 1
Solution
x = {-13, 1}
