f(a)=a^2-7a-9 f(a+h)=a^2+2ah+h^2-7a-7h-9 (a+h)^2=a^2+2ah+h^2 just so you know 2ah+h^2-7h=f(a+h)-f(a)

OpenStudy (anonymous):

so the final answer is 2ah+g^2-7h=f(a+h)-f(a) ?....

OpenStudy (anonymous):

h^2 not g^2 but yea.

OpenStudy (anonymous):

oops, typo- thank you!

OpenStudy (anonymous):

but if you simplify its h(2a+h-7)
