How would you solve (2x+16)/(x+6)(x+7) in partial fractions?

This is a simple partial fraction to solve as the denominator has already been given to you as a factorised quadratic. Because the x terms are to the dgree 1 aka x 1 we use the form (2x+16)/(x+6)(x+7) = A/(x...

find the value of x for when f(x)=0. f(x)=9x^(2)-4

since f(x)=0 write 9x 2 -4=0 move the x's to one side and the numbers to the other. so 9x 2 =4 then to get rid of the 9 divide both sides by 9 so x 2 =(4/9) then square root so x=sqrt(4/9) and simply by taki...

How would you differentiate f(x) = 2x(3x - 1)^2 using the chain rule?

In order to differentiate this expression, you need to use the chain rule. The chain rule gives: f'(x) = uv' + u'v. The u and the v are two parts of the original function f(x). The apostrophe ' at the end me...
