Solution for 180=(2x+13)*(2x+10) equation:


Simplifying
180 = (2x + 13)(2x + 10)

Reorder the terms:
180 = (13 + 2x)(2x + 10)

Reorder the terms:
180 = (13 + 2x)(10 + 2x)

Multiply (13 + 2x) * (10 + 2x)
180 = (13(10 + 2x) + 2x * (10 + 2x))
180 = ((10 * 13 + 2x * 13) + 2x * (10 + 2x))
180 = ((130 + 26x) + 2x * (10 + 2x))
180 = (130 + 26x + (10 * 2x + 2x * 2x))
180 = (130 + 26x + (20x + 4x2))

Combine like terms: 26x + 20x = 46x
180 = (130 + 46x + 4x2)

Solving
180 = 130 + 46x + 4x2

Solving for variable 'x'.

Combine like terms: 180 + -130 = 50
50 + -46x + -4x2 = 130 + 46x + 4x2 + -130 + -46x + -4x2

50 + -46x + -4x2 = 130 + -130 + 46x + -46x + 4x2 + -4x2

Combine like terms: 130 + -130 = 0
50 + -46x + -4x2 = 0 + 46x + -46x + 4x2 + -4x2
50 + -46x + -4x2 = 46x + -46x + 4x2 + -4x2

Combine like terms: 46x + -46x = 0
50 + -46x + -4x2 = 0 + 4x2 + -4x2
50 + -46x + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
50 + -46x + -4x2 = 0

Subproblem 1

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

Subproblem 2

Set the factor '(25 + 2x)' equal to zero and attempt to solve: Simplifying 25 + 2x = 0 Solving 25 + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + 2x = 0 + -25 Combine like terms: 25 + -25 = 0 0 + 2x = 0 + -25 2x = 0 + -25 Combine like terms: 0 + -25 = -25 2x = -25 Divide each side by '2'. x = -12.5 Simplifying x = -12.5

Solution

x = {1, -12.5}
