Solution for F(x)=(x-1)(x+9) equation: 


Simplifying
F(x) = (x + -1)(x + 9)

Multiply F * x
xF = (x + -1)(x + 9)

Reorder the terms:
xF = (-1 + x)(x + 9)

Reorder the terms:
xF = (-1 + x)(9 + x)

Multiply (-1 + x) * (9 + x)
xF = (-1(9 + x) + x(9 + x))
xF = ((9 * -1 + x * -1) + x(9 + x))
xF = ((-9 + -1x) + x(9 + x))
xF = (-9 + -1x + (9 * x + x * x))
xF = (-9 + -1x + (9x + x2))

Combine like terms: -1x + 9x = 8x
xF = (-9 + 8x + x2)

Solving
xF = -9 + 8x + x2

Solving for variable 'x'.

Reorder the terms:
9 + -8x + xF + -1x2 = -9 + 8x + x2 + 9 + -8x + -1x2

Reorder the terms:
9 + -8x + xF + -1x2 = -9 + 9 + 8x + -8x + x2 + -1x2

Combine like terms: -9 + 9 = 0
9 + -8x + xF + -1x2 = 0 + 8x + -8x + x2 + -1x2
9 + -8x + xF + -1x2 = 8x + -8x + x2 + -1x2

Combine like terms: 8x + -8x = 0
9 + -8x + xF + -1x2 = 0 + x2 + -1x2
9 + -8x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
9 + -8x + xF + -1x2 = 0
