document.write( "Question 494627: I am having a hard time with multiplying out (2+h)^3. I have tried to do
\n" ); document.write( "(2+h)(2+h)(2+h) and did (2^2+2h+h^2)= (4+2h+h^2) . I am using this in Derivatives. \r

\n" ); document.write( "\n" ); document.write( "So F'(2+h)= ((2+h))^3 Which is (4+2h+h^2)
\n" ); document.write( "Then F'(2)= (2)^3 Which is (8)\r
\n" ); document.write( "\n" ); document.write( "So then I take (4+2h+h^2)-(8)\r
\n" ); document.write( "\n" ); document.write( "and I get -4+2h+h^2/h Do you see my problem.\r
