I'm assuming that you mean 2b%5E2%2B13b-7=0


2b%5E2%2B13b-7=0 Start with the given equation

%28b%2B7%29%282b-1%29=0 Factor the left side (note: if you need help with factoring, check out this solver)



Now set each factor equal to zero:
b%2B7=0 or 2b-1=0

b=-7 or b=1%2F2 Now solve for b in each case


So our answers are

b=-7 or b=1%2F2
