Solution for g(x)=(4-x)(2+7x) equation:


Simplifying
g(x) = (4 + -1x)(2 + 7x)

Multiply g * x
gx = (4 + -1x)(2 + 7x)

Multiply (4 + -1x) * (2 + 7x)
gx = (4(2 + 7x) + -1x * (2 + 7x))
gx = ((2 * 4 + 7x * 4) + -1x * (2 + 7x))
gx = ((8 + 28x) + -1x * (2 + 7x))
gx = (8 + 28x + (2 * -1x + 7x * -1x))
gx = (8 + 28x + (-2x + -7x2))

Combine like terms: 28x + -2x = 26x
gx = (8 + 26x + -7x2)
