(2x-6)(x+3)=f(x)

Solution for (2x-6)(x+3)=f(x) equation:

Simplifying
(2x + -6)(x + 3) = f(x)

Reorder the terms:
(-6 + 2x)(x + 3) = f(x)

Reorder the terms:
(-6 + 2x)(3 + x) = f(x)

Multiply (-6 + 2x) * (3 + x)
(-6(3 + x) + 2x * (3 + x)) = f(x)
((3 * -6 + x * -6) + 2x * (3 + x)) = f(x)
((-18 + -6x) + 2x * (3 + x)) = f(x)
(-18 + -6x + (3 * 2x + x * 2x)) = f(x)
(-18 + -6x + (6x + 2x2)) = f(x)

Combine like terms: -6x + 6x = 0
(-18 + 0 + 2x2) = f(x)
(-18 + 2x2) = f(x)

Multiply f * x
-18 + 2x2 = fx

Solving
-18 + 2x2 = fx

Solving for variable 'x'.

Reorder the terms:
-18 + -1fx + 2x2 = fx + -1fx

Combine like terms: fx + -1fx = 0
-18 + -1fx + 2x2 = 0
