3x%5E2%2Bx-0=0 Start with the given equation


3x%5E2%2Bx=0 Remove the zero term on the left



x%283x%2B1%29=0 Factor the left side


Now set each factor equal to zero:
x=0 or 3x%2B1=0

x=0 or x=-1%2F3 Now solve for x in each case


So our answer is
x=0 or x=-1%2F3


Notice if we graph y=3x%5E2%2Bx-0 we can see that the roots are x=0 and x=-1%2F3 . So this visually verifies our answer.
