Question

Algebra question: 3(x+h)^2

Answer 1

not sure what to do first

Answer 2

3(x+h)(x+h)
3(x^2 + 2xh + h^2)
3x^2 + 6xh + 3h^2

if your just expanding the brackets, is that what your after?

Answer 3

uhh, well I am doing definition of derivative and i'm not sure I was expecting polynomials

Answer 4

is that the absolute way of solving that? @JamesWolf

Answer 5

never mind, thanks

Answer 6

well what is it equal too?
you have 2 unknowns and 1 equation. what are you solving it for. your trying to take the derivative with respect to x? is h constant? sortof need to know these things to help

Answer 7

derivative will be
u = x +h
f(x) = 3(u)^2

df(x)/dx = df(x)/du x du/dx

= 6(u) x 1 = 6(u) = 6(x+h)

Answer 8

Thank you, I got it from there :)
