True:1/4 is an example of a terminating decimal
I believe one answer could be (4x4)=16-10=6+12=18+10=28-4=24?
It's the graphs that don't touch the x-axis have complex roots. Roots are the points where the parabola touches the x-axis. A,C and E all cross/touch the x-axis so they have real roots.
non-real or complex root parabolas are: B, D, F
