How do you find the number of roots for #f(x) = x^3 + 2x^2 - 24x# using the fundamental theorem of algebra?
This theorem just tells you that a polynomial
1st of all, you can factorize by
Before using this theorem, we need to know if P(x) =
You first calculate
By using the quadratic formula, we find out that the two roots of P are
I hope it helped you.
