Solution for 2(x-4)(x+10)=0 equation:

Simplifying
2(x + -4)(x + 10) = 0

Reorder the terms:
2(-4 + x)(x + 10) = 0

Reorder the terms:
2(-4 + x)(10 + x) = 0

Multiply (-4 + x) * (10 + x)
2(-4(10 + x) + x(10 + x)) = 0
2((10 * -4 + x * -4) + x(10 + x)) = 0
2((-40 + -4x) + x(10 + x)) = 0
2(-40 + -4x + (10 * x + x * x)) = 0
2(-40 + -4x + (10x + x2)) = 0

Combine like terms: -4x + 10x = 6x
2(-40 + 6x + x2) = 0
(-40 * 2 + 6x * 2 + x2 * 2) = 0
(-80 + 12x + 2x2) = 0

Solving
-80 + 12x + 2x2 = 0

Subproblem 1
Set the factor '(-10 + -1x)' equal to zero and attempt to solve:

Simplifying
-10 + -1x = 0

Solving
-10 + -1x = 0

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

Add '10' to each side of the equation.
-10 + 10 + -1x = 0 + 10

Combine like terms: -10 + 10 = 0
0 + -1x = 0 + 10
-1x = 0 + 10

Combine like terms: 0 + 10 = 10
-1x = 10

Divide each side by '-1'.
x = -10

Simplifying
x = -10
Subproblem 2
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
Solution
x = {-10, 4}
