34=(x+11)(x-4)

Solution for 34=(x+11)(x-4) equation:

Simplifying
34 = (x + 11)(x + -4)

Reorder the terms:
34 = (11 + x)(x + -4)

Reorder the terms:
34 = (11 + x)(-4 + x)

Multiply (11 + x) * (-4 + x)
34 = (11(-4 + x) + x(-4 + x))
34 = ((-4 * 11 + x * 11) + x(-4 + x))
34 = ((-44 + 11x) + x(-4 + x))
34 = (-44 + 11x + (-4 * x + x * x))
34 = (-44 + 11x + (-4x + x2))

Combine like terms: 11x + -4x = 7x
34 = (-44 + 7x + x2)

Solving
34 = -44 + 7x + x2

Solving for variable 'x'.

Combine like terms: 34 + 44 = 78
78 + -7x + -1x2 = -44 + 7x + x2 + 44 + -7x + -1x2

Reorder the terms:
78 + -7x + -1x2 = -44 + 44 + 7x + -7x + x2 + -1x2

Combine like terms: -44 + 44 = 0
78 + -7x + -1x2 = 0 + 7x + -7x + x2 + -1x2
78 + -7x + -1x2 = 7x + -7x + x2 + -1x2

Combine like terms: 7x + -7x = 0
78 + -7x + -1x2 = 0 + x2 + -1x2
78 + -7x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
78 + -7x + -1x2 = 0

Divide each side by '-1'.
x = 6

Simplifying
x = 6
Subproblem 2
Set the factor '(13 + x)' equal to zero and attempt to solve:

Simplifying
13 + x = 0

Solving
13 + x = 0

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

Add '-13' to each side of the equation.
13 + -13 + x = 0 + -13

Combine like terms: 13 + -13 = 0
0 + x = 0 + -13
x = 0 + -13

Combine like terms: 0 + -13 = -13
x = -13

Simplifying
x = -13
Solution
x = {6, -13}
