Solution for H(x)=(2-x)(5+x) equation: 


Simplifying
H(x) = (2 + -1x)(5 + x)

Multiply H * x
xH = (2 + -1x)(5 + x)

Multiply (2 + -1x) * (5 + x)
xH = (2(5 + x) + -1x * (5 + x))
xH = ((5 * 2 + x * 2) + -1x * (5 + x))
xH = ((10 + 2x) + -1x * (5 + x))
xH = (10 + 2x + (5 * -1x + x * -1x))
xH = (10 + 2x + (-5x + -1x2))

Combine like terms: 2x + -5x = -3x
xH = (10 + -3x + -1x2)

Solving
xH = 10 + -3x + -1x2

Solving for variable 'x'.
