Question

Please help!!!!!!
One root of f(x)=2x^3+9x^2+7x-6 is -3 explain how to find the factors of the polynomial

Answer 1

Since we know one root, which is -3, we can use synthetic division to find (x+3) would need to be multiplied by to get the original polynomial. Then, we factor the quadratic to find the other two factors, which are 1/2 and -2
