=(x^2+x-1)(x+1)

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

Simplifying
0 = (x2 + x + -1)(x + 1)

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

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

Multiply (-1 + x + x2) * (1 + x)
0 = (-1(1 + x) + x(1 + x) + x2(1 + x))
0 = ((1 * -1 + x * -1) + x(1 + x) + x2(1 + x))
0 = ((-1 + -1x) + x(1 + x) + x2(1 + x))
0 = (-1 + -1x + (1 * x + x * x) + x2(1 + x))
0 = (-1 + -1x + (1x + x2) + x2(1 + x))
0 = (-1 + -1x + 1x + x2 + (1 * x2 + x * x2))
0 = (-1 + -1x + 1x + x2 + (1x2 + x3))

Combine like terms: -1x + 1x = 0
0 = (-1 + 0 + x2 + 1x2 + x3)
0 = (-1 + x2 + 1x2 + x3)

Combine like terms: x2 + 1x2 = 2x2
0 = (-1 + 2x2 + x3)

Solving
0 = -1 + 2x2 + x3

Solving for variable 'x'.

Combine like terms: 0 + 1 = 1
1 + -2x2 + -1x3 = -1 + 2x2 + x3 + 1 + -2x2 + -1x3

Reorder the terms:
1 + -2x2 + -1x3 = -1 + 1 + 2x2 + -2x2 + x3 + -1x3

Combine like terms: -1 + 1 = 0
1 + -2x2 + -1x3 = 0 + 2x2 + -2x2 + x3 + -1x3
1 + -2x2 + -1x3 = 2x2 + -2x2 + x3 + -1x3

Combine like terms: 2x2 + -2x2 = 0
1 + -2x2 + -1x3 = 0 + x3 + -1x3
1 + -2x2 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
1 + -2x2 + -1x3 = 0
