Is there a way to solve that using the below methods?

Substitute zero for f(x) and find the roots of the resulting equation, or graph the function and determine the x-intercepts of the graph.

Finding the roots of a single variable equation may involve factoring. Except in the case of a linear equation, set the equation to zero before factoring. Recall the following techniques for factoring: common factors, difference of two squares, trinomials in the form x^2+bx+c=0, and trinomials of the form ax^2+bx+c=0

either 2x=0 or x+3=0 so

x=0; or -3
