i cant tell you how many different answers i keep getting for these 3 even after comparing with a few of my friends. Frustrated to the max

it says find the roots in simplest radical form,

first one
3x^2 - 5x - 1 = 0

second
2x^2 - 2x = 3

third
2x^2 - 10x = 9

Any help please! you will be thanked.

2. Hope this helps
