You didn't specify a method to use to solve for roots.
First step is to plot it to see if there are real roots.
.
So there is a root between x=-1 and x=0.
I'll use Newton's method to find it with a starting value of x=-0.5
f%28x%29=x%5E3%2B4x%2B3
df%2Fdx=3x%5E2%2B4

x=-0.67359
The other two roots are complex.
