I want to solve using the quadratic formula, but I don't have "b" from the form. axsquare + bx+ c=0. What number should I put for b in the formula?

Answer provided by our tutors

Your equations is

2n^2 + 2 = 0 

Since there is no term with "n" this means "b = 0", so you need to put "0" for "b" into the quadratic formula.
