f(x+h)=-x^2+x

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

Simplifying
f(x + h) = -1x2 + x

Reorder the terms:
f(h + x) = -1x2 + x
(h * f + x * f) = -1x2 + x
(fh + fx) = -1x2 + x

Reorder the terms:
fh + fx = x + -1x2

Solving
fh + fx = x + -1x2

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Reorder the terms:
fh + fx + -1x + x2 = x + -1x + -1x2 + x2

Combine like terms: x + -1x = 0
fh + fx + -1x + x2 = 0 + -1x2 + x2
fh + fx + -1x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
fh + fx + -1x + x2 = 0
