(x-2)(x+10)=

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

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

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

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

Multiply (-2 + x) * (10 + x)
(-2(10 + x) + x(10 + x)) = 0
((10 * -2 + x * -2) + x(10 + x)) = 0
((-20 + -2x) + x(10 + x)) = 0
(-20 + -2x + (10 * x + x * x)) = 0
(-20 + -2x + (10x + x2)) = 0

Combine like terms: -2x + 10x = 8x
(-20 + 8x + x2) = 0

Solving
-20 + 8x + x2 = 0

Solving for variable 'x'.

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
Solution
x = {-10, 2}
