agree with math guy, but did you copy the qn wrongly?
because if it is
0.5x^2-1.5x-2=0
or
-0.5x^2+1.5x+2=0
x = 4 or x = -1
which is a nicer ans haha

Assume equation is:-
0.5 x² + 1.5 x + 2 = 0
x² + 3x + 4 = 0
x = [- 3 ± â(-7)] / 2
x = [- 3 ± â(7) i ] / 2

just make it so the two numbers with the "x"s attacted to them are equal. then you can take them away and just use teh exponent.
