(x*x)+(x*-1)+(x*x)+(x*1)=

Solution for (x*x)+(x*-1)+(x*x)+(x*1)= equation:

Simplifying
(x * x) + (x * -1) + (x * x) + (x * 1) = 0

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

Reorder the terms for easier multiplication:
x2 + (-1x) + (x * x) + (x * 1) = 0

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

Reorder the terms for easier multiplication:
x2 + (-1x) + x2 + (1x) = 0

Reorder the terms:
(-1x) + (1x) + x2 + x2 = 0

Combine like terms: (-1x) + (1x) = 0
0 + x2 + x2 = 0
x2 + x2 = 0

Combine like terms: x2 + x2 = 2x2
2x2 = 0

Solving
2x2 = 0

Solving for variable 'x'.

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

Divide each side by '2'.
x2 = 0

Simplifying
x2 = 0

Take the square root of each side:
x = {0}
