4x%5E2-1=0 Start with the given equation

%282x%2B1%29%282x-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:
2x%2B1=0 or 2x-1=0

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


So the answer is

x=-1%2F2 (with a multiplicity of 2)
