(2x+8)(x-3)=

Solution for (2x+8)(x-3)= equation:

Simplifying
(2x + 8)(x + -3) = 0

Reorder the terms:
(8 + 2x)(x + -3) = 0

Reorder the terms:
(8 + 2x)(-3 + x) = 0

Multiply (8 + 2x) * (-3 + x)
(8(-3 + x) + 2x * (-3 + x)) = 0
((-3 * 8 + x * 8) + 2x * (-3 + x)) = 0
((-24 + 8x) + 2x * (-3 + x)) = 0
(-24 + 8x + (-3 * 2x + x * 2x)) = 0
(-24 + 8x + (-6x + 2x2)) = 0

Combine like terms: 8x + -6x = 2x
(-24 + 2x + 2x2) = 0

Solving
-24 + 2x + 2x2 = 0

Subproblem 1
Set the factor '(-4 + -1x)' equal to zero and attempt to solve:

Simplifying
-4 + -1x = 0

Solving
-4 + -1x = 0

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

Add '4' to each side of the equation.
-4 + 4 + -1x = 0 + 4

Combine like terms: -4 + 4 = 0
0 + -1x = 0 + 4
-1x = 0 + 4

Combine like terms: 0 + 4 = 4
-1x = 4

Divide each side by '-1'.
x = -4

Simplifying
x = -4
Subproblem 2
Set the factor '(3 + -1x)' equal to zero and attempt to solve:

Simplifying

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

Add '-3' to each side of the equation.
3 + -3 + -1x = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1x = 0 + -3
-1x = 0 + -3

Combine like terms: 0 + -3 = -3
-1x = -3

Divide each side by '-1'.
x = 3

Simplifying
x = 3
Solution
x = {-4, 3}
