2x^2+3x=2x is the same as rewriting it as 2x^2-2x+3=0
The zeros using the quadratic formula. A=1 B= -2 C= 3
I ended up with
x=1/2(1+ i√5) also written as 1/2 + i√5/2
Both will give you the same answer
The other solution is
x=1/2(1-i√5) or 1/2-i√5/2
IMPORTANT: when writing the i√5/2 part the 2 is NOT under the radical with the 5 it is the entire component over 2
