7a%5E2%2B9a%2B2=0 Start with the given equation

%28a%2B1%29%287a%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:
a%2B1=0 or 7a%2B2=0

a=-1 or a=-2%2F7 Now solve for a in each case


So our answer is
a=-1 or a=-2%2F7
