Sorry for the late reply but yea i solved the problem during the test. So basically i find the derivative of h(x) it is not the same as h'(x) that they provided you in the question. Then you just equate your derived h'(x) to the given h'(x), isolate for f(x). Although on the test it was f'(x) so...
Homework Statement
h(x)=(5-5x2)f(x) h'(x)=6xf(x)+4x4+2x2
Homework Equations
Find f(x)
The Attempt at a Solution
I tried finding h'(x) from the first part and then equating the two, but this does not seem to work. Urgent help required TEST in 2 hours! The general method may be...
