Solution for g(x)=.5(2x+10)(x-3) equation:


Simplifying
g(x) = 0.5(2x + 10)(x + -3)

Multiply g * x
gx = 0.5(2x + 10)(x + -3)

Reorder the terms:
gx = 0.5(10 + 2x)(x + -3)

Reorder the terms:
gx = 0.5(10 + 2x)(-3 + x)

Multiply (10 + 2x) * (-3 + x)
gx = 0.5(10(-3 + x) + 2x * (-3 + x))
gx = 0.5((-3 * 10 + x * 10) + 2x * (-3 + x))
gx = 0.5((-30 + 10x) + 2x * (-3 + x))
gx = 0.5(-30 + 10x + (-3 * 2x + x * 2x))
gx = 0.5(-30 + 10x + (-6x + 2x2))

Combine like terms: 10x + -6x = 4x
gx = 0.5(-30 + 4x + 2x2)
gx = (-30 * 0.5 + 4x * 0.5 + 2x2 * 0.5)
gx = (-15 + 2x + 1x2)

Solving
gx = -15 + 2x + 1x2
