Solution for y=2x(x-1)-(x^2+2)1 equation: 


Simplifying
y = 2x(x + -1) + -1(x2 + 2) * 1

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

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

Reorder the terms for easier multiplication:
y = -2x + 2x2 + -1 * 1(2 + x2)

Multiply -1 * 1
y = -2x + 2x2 + -1(2 + x2)
y = -2x + 2x2 + (2 * -1 + x2 * -1)
y = -2x + 2x2 + (-2 + -1x2)

Reorder the terms:
y = -2 + -2x + 2x2 + -1x2

Combine like terms: 2x2 + -1x2 = 1x2
y = -2 + -2x + 1x2
