Step-by-step explanation:
3x²-x-2=0
3x²-3x+2x-2=0
3x(x-1)+2(x-1)=0
(x-1)(3x+2)=0
(x-1)=0 or (3x+2)=0
x=1 or 3x=-2
x=1 or x=-2/3
the roots of equation is 1 and -2/3.

Answer:
3x²-x-2 = 0
3x²-(3-2)x-2 = 0
3x²-3x+2x-2 = 0
3x(x-1)+2(x-1) = 0
(x-1)(3x+2) = 0
Either (x-1) = 0 or (3x+2) = 0
Either x = 1 or x = -2/3
