What is 2 n squared it should =-144. I'M TRYING TO SOLVE FOR N.
The solution to your problem is a "complex number solution", which is:
n = ±(6 i)
It can't possibly be that!!!
2n2 = -144 divide by 2 on both sides
n2 = -72 take the positive and negative roots of both sides
n = (plus/minus)sqrt(-72)
n = (plus/munus)( 6i ) * sqrt(2)
