0=(-x-8)(-x+6)

Solution for 0=(-x-8)(-x+6) equation:

Simplifying
0 = (-1x + -8)(-1x + 6)

Reorder the terms:
0 = (-8 + -1x)(-1x + 6)

Reorder the terms:
0 = (-8 + -1x)(6 + -1x)

Multiply (-8 + -1x) * (6 + -1x)
0 = (-8(6 + -1x) + -1x * (6 + -1x))
0 = ((6 * -8 + -1x * -8) + -1x * (6 + -1x))
0 = ((-48 + 8x) + -1x * (6 + -1x))
0 = (-48 + 8x + (6 * -1x + -1x * -1x))
0 = (-48 + 8x + (-6x + 1x2))

Combine like terms: 8x + -6x = 2x
0 = (-48 + 2x + 1x2)

Solving
0 = -48 + 2x + 1x2

Solving for variable 'x'.

Combine like terms: 0 + 48 = 48
48 + -2x + -1x2 = -48 + 2x + 1x2 + 48 + -2x + -1x2

Reorder the terms:
48 + -2x + -1x2 = -48 + 48 + 2x + -2x + 1x2 + -1x2

Combine like terms: -48 + 48 = 0
48 + -2x + -1x2 = 0 + 2x + -2x + 1x2 + -1x2
48 + -2x + -1x2 = 2x + -2x + 1x2 + -1x2

Combine like terms: 2x + -2x = 0
48 + -2x + -1x2 = 0 + 1x2 + -1x2
48 + -2x + -1x2 = 1x2 + -1x2

Combine like terms: 1x2 + -1x2 = 0
48 + -2x + -1x2 = 0
