real or imaginary solutions
84. 3y^2 + 4y � 1 = 0
We use the discriminant to determine if there are real or imaginary solutions. If the discriminant is negative there are two imaginary solutions. If it's positive there are two real solutions. If it's 0 there is one real solution.
The discriminant is
a=3, b=4, and c=-1

It's positive so there's two real solutions. Because this is not a perfect square you have to use the quadratice formula if you have to solve it. (you could complete the square, but because a is 3, you would have to deal with fractions.)
