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

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

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

Multiply x * x
2x2 = 8(x + 3)

Reorder the terms:
2x2 = 8(3 + x)
2x2 = (3 * 8 + x * 8)
2x2 = (24 + 8x)

Solving
2x2 = 24 + 8x

Solving for variable 'x'.

Reorder the terms:
-24 + -8x + 2x2 = 24 + 8x + -24 + -8x

Reorder the terms:
-24 + -8x + 2x2 = 24 + -24 + 8x + -8x

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

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

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

Simplifying
-2 + -1x = 0

Solving
-2 + -1x = 0

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

Add '2' to each side of the equation.
-2 + 2 + -1x = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -1x = 0 + 2
-1x = 0 + 2

Combine like terms: 0 + 2 = 2
-1x = 2

Divide each side by '-1'.
x = -2

Simplifying
x = -2
Subproblem 2
Set the factor '(6 + -1x)' equal to zero and attempt to solve:

Simplifying
6 + -1x = 0

Solving
6 + -1x = 0

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

Add '-6' to each side of the equation.
6 + -6 + -1x = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1x = 0 + -6
-1x = 0 + -6

Combine like terms: 0 + -6 = -6
-1x = -6

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

Simplifying
x = 6
Solution
x = {-2, 6}
