Solution for f(x)=(x+5)(x-6) equation:


Simplifying
f(x) = (x + 5)(x + -6)

Multiply f * x
fx = (x + 5)(x + -6)

Reorder the terms:
fx = (5 + x)(x + -6)

Reorder the terms:
fx = (5 + x)(-6 + x)

Multiply (5 + x) * (-6 + x)
fx = (5(-6 + x) + x(-6 + x))
fx = ((-6 * 5 + x * 5) + x(-6 + x))
fx = ((-30 + 5x) + x(-6 + x))
fx = (-30 + 5x + (-6 * x + x * x))
fx = (-30 + 5x + (-6x + x2))

Combine like terms: 5x + -6x = -1x
fx = (-30 + -1x + x2)

Solving
fx = -30 + -1x + x2
