SOLUTION: Evaluate and simplify {{{ f(x+h)/h -f(x)/h }}} if h≠0 and {{{ f(x)= x^2-3x+5 }}}

Question 838124: Evaluate and simplify if h≠0 and

f(x+h)/h -f(x)/h if h # 0 and f(x)= x^2-3x+5
-----------
f(x+h) = (x+h)^2-3(x+h)+5 = x^2+2hx+h^2-3x-3h+5
-----
Subtracting f(x) you get::
= 2hx + h^2-3h
-----
Dividng by "h" you get:
= 2x + h - 3
