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


Simplifying
2x + -1(2 + -1x)(4 + x) = -1(2 + -1x)(2 + x)

Multiply (2 + -1x) * (4 + x)
2x + -1(2(4 + x) + -1x * (4 + x)) = -1(2 + -1x)(2 + x)
2x + -1((4 * 2 + x * 2) + -1x * (4 + x)) = -1(2 + -1x)(2 + x)
2x + -1((8 + 2x) + -1x * (4 + x)) = -1(2 + -1x)(2 + x)
2x + -1(8 + 2x + (4 * -1x + x * -1x)) = -1(2 + -1x)(2 + x)
2x + -1(8 + 2x + (-4x + -1x2)) = -1(2 + -1x)(2 + x)

Combine like terms: 2x + -4x = -2x
2x + -1(8 + -2x + -1x2) = -1(2 + -1x)(2 + x)
2x + (8 * -1 + -2x * -1 + -1x2 * -1) = -1(2 + -1x)(2 + x)
2x + (-8 + 2x + 1x2) = -1(2 + -1x)(2 + x)

Reorder the terms:
-8 + 2x + 2x + 1x2 = -1(2 + -1x)(2 + x)

Combine like terms: 2x + 2x = 4x
-8 + 4x + 1x2 = -1(2 + -1x)(2 + x)

Multiply (2 + -1x) * (2 + x)
-8 + 4x + 1x2 = -1(2(2 + x) + -1x * (2 + x))
-8 + 4x + 1x2 = -1((2 * 2 + x * 2) + -1x * (2 + x))
-8 + 4x + 1x2 = -1((4 + 2x) + -1x * (2 + x))
-8 + 4x + 1x2 = -1(4 + 2x + (2 * -1x + x * -1x))
-8 + 4x + 1x2 = -1(4 + 2x + (-2x + -1x2))

Combine like terms: 2x + -2x = 0
-8 + 4x + 1x2 = -1(4 + 0 + -1x2)
-8 + 4x + 1x2 = -1(4 + -1x2)
-8 + 4x + 1x2 = (4 * -1 + -1x2 * -1)
-8 + 4x + 1x2 = (-4 + 1x2)

Add '-1x2' to each side of the equation.
-8 + 4x + 1x2 + -1x2 = -4 + 1x2 + -1x2
