Question 152517: g(2+h)=x to the third
the instructor gave us x=(2+h)
and the answer 8+12h+6h suared+h to the third
i haven't been able to get that as my answer.
here's what I have done:
g(2+h)=x to the third
g=(2+h)to the third
g=(2+h)(2+h)(2+h)
g=4+2h+2h+hsquared(2+h)
g=8+4h+4h+2h+2h+2hsquared+h to the third
g=8+12h+2hsquared+h to the third: g(2+h)=x to the third
the instructor gave us x=(2+h)
and the answer 8+12h+6h suared+h to the third
i haven't been able to get that as my answer.
here's what I have done:
g(2+h)=x to the third
g=(2+h)to the third
g=(2+h)(2+h)(2+h)
g=4+2h+2h+hsquared(2+h)
g=8+4h+4h+2h+2h+2hsquared+h to the third
g=8+12h+2hsquared+h to the third

Question 152274: [(x^3 - 1)/(x^2 +1)] divided by (9x^2 + 9x + 9)/ (x^2 - x)
= (x-1) (x^2 + x +1)/(x^2 +1) divided by [ 9(x^2 + x + 1)]/[ x (x-1)]
= [(x-1)(x^2 + x + 1)/ (x^2 + 1) ] [x (x-1)/9(x^2 + x + 1)]
= [x (x-1)(x-1) / 9(x^2 + 1)]
can this be simplified more? is this correct?
