-2(x-1)(x-5)=0

Solution for -2(x-1)(x-5)=0 equation:

Simplifying
-2(x + -1)(x + -5) = 0

Reorder the terms:
-2(-1 + x)(x + -5) = 0

Reorder the terms:
-2(-1 + x)(-5 + x) = 0

Multiply (-1 + x) * (-5 + x)
-2(-1(-5 + x) + x(-5 + x)) = 0
-2((-5 * -1 + x * -1) + x(-5 + x)) = 0
-2((5 + -1x) + x(-5 + x)) = 0
-2(5 + -1x + (-5 * x + x * x)) = 0
-2(5 + -1x + (-5x + x2)) = 0

Combine like terms: -1x + -5x = -6x
-2(5 + -6x + x2) = 0
(5 * -2 + -6x * -2 + x2 * -2) = 0
(-10 + 12x + -2x2) = 0

Solving
-10 + 12x + -2x2 = 0

Subproblem 1
Set the factor '(-5 + x)' equal to zero and attempt to solve:

Simplifying
-5 + x = 0

Solving
-5 + x = 0

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

Add '5' to each side of the equation.
-5 + 5 + x = 0 + 5

Combine like terms: -5 + 5 = 0
0 + x = 0 + 5
x = 0 + 5

x = 5

Simplifying
x = 5
Subproblem 2
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
Solution
x = {5, 1}
