Solution for f(a+h)-f(a)=2x^2+3x-7 equation:


Simplifying
f(a + h) + -1f(a) = 2x2 + 3x + -7
(a * f + h * f) + -1f(a) = 2x2 + 3x + -7
(af + fh) + -1f(a) = 2x2 + 3x + -7

Multiply f * a
af + fh + -1af = 2x2 + 3x + -7

Reorder the terms:
af + -1af + fh = 2x2 + 3x + -7

Combine like terms: af + -1af = 0
0 + fh = 2x2 + 3x + -7
fh = 2x2 + 3x + -7

Reorder the terms:
fh = -7 + 3x + 2x2

Solving
fh = -7 + 3x + 2x2
