(a) Find f'(x) if
f(x) = ((2x ^ 2 - 1)(x ^ 2 + 3sqrt(x)))/(x ^ 3 + 2sqrt(x))
2 answers
f(x) = ((2x^2 - 1)(x^2 + 3√x))/(x^3 + 2√x)
consider this as f(x) = u/v where u and v are functions of x. Then, using the quotient rule,
f'(x) = (u'v - uv')/v^2
Now, u' can be found using the product rule, so we have
f'(x) = (((4x)(x^2 + 3√x))+(3x^2-1)(2x + 3/(2√x)))(x^2 + 3√x) - ((2x^2 - 1)(x^2 + 3√x))(3x^2 + 1/√x)) / (x^3 + 2√x)^2
Now simplify that! You should get something like
x[4x^5+2x^3+48 + √x (28x^2+15x-6)]
