Solution for F(x)=(x-9)(x+3) equation: 


Simplifying
F(x) = (x + -9)(x + 3)

Multiply F * x
xF = (x + -9)(x + 3)

Reorder the terms:
xF = (-9 + x)(x + 3)

Reorder the terms:
xF = (-9 + x)(3 + x)

Multiply (-9 + x) * (3 + x)
xF = (-9(3 + x) + x(3 + x))
xF = ((3 * -9 + x * -9) + x(3 + x))
xF = ((-27 + -9x) + x(3 + x))
xF = (-27 + -9x + (3 * x + x * x))
xF = (-27 + -9x + (3x + x2))

Combine like terms: -9x + 3x = -6x
xF = (-27 + -6x + x2)

Solving
xF = -27 + -6x + x2

Solving for variable 'x'.

Reorder the terms:
27 + 6x + xF + -1x2 = -27 + -6x + x2 + 27 + 6x + -1x2

Reorder the terms:
27 + 6x + xF + -1x2 = -27 + 27 + -6x + 6x + x2 + -1x2

Combine like terms: -27 + 27 = 0
27 + 6x + xF + -1x2 = 0 + -6x + 6x + x2 + -1x2
27 + 6x + xF + -1x2 = -6x + 6x + x2 + -1x2

Combine like terms: -6x + 6x = 0
27 + 6x + xF + -1x2 = 0 + x2 + -1x2
27 + 6x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
27 + 6x + xF + -1x2 = 0
