You can put this solution on YOUR website!

m%5E2-3m-10=0 Start with the given equation

%28m-5%29%28m%2B2%29=0 Factor the left side (note: if you need help with factoring, check out this solver)



Now set each factor equal to zero:
m-5=0 or m%2B2=0

m=5 or m=-2 Now solve for m in each case


So our answer is
m=5 or m=-2


Notice if we graph y=x%5E2-3x-10 (just replace m with x) we can see that the roots are x=5 and x=-2 . So this visually verifies our answer.
