Solution for F(x)=(x-9)(x-5) equation: 


Simplifying
F(x) = (x + -9)(x + -5)

Multiply F * x
xF = (x + -9)(x + -5)

Reorder the terms:
xF = (-9 + x)(x + -5)

Reorder the terms:
xF = (-9 + x)(-5 + x)

Multiply (-9 + x) * (-5 + x)
xF = (-9(-5 + x) + x(-5 + x))
xF = ((-5 * -9 + x * -9) + x(-5 + x))
xF = ((45 + -9x) + x(-5 + x))
xF = (45 + -9x + (-5 * x + x * x))
xF = (45 + -9x + (-5x + x2))

Combine like terms: -9x + -5x = -14x
xF = (45 + -14x + x2)

Solving
xF = 45 + -14x + x2

Solving for variable 'x'.

Reorder the terms:
-45 + 14x + xF + -1x2 = 45 + -14x + x2 + -45 + 14x + -1x2

Reorder the terms:
-45 + 14x + xF + -1x2 = 45 + -45 + -14x + 14x + x2 + -1x2

Combine like terms: 45 + -45 = 0
-45 + 14x + xF + -1x2 = 0 + -14x + 14x + x2 + -1x2
-45 + 14x + xF + -1x2 = -14x + 14x + x2 + -1x2

Combine like terms: -14x + 14x = 0
-45 + 14x + xF + -1x2 = 0 + x2 + -1x2
-45 + 14x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-45 + 14x + xF + -1x2 = 0
