Can someone me with 11? i’m confused on how to solve for the rest of the problem. i don’t know how to get rid of the 3

3x^2-7x+2=0

Use the slip and slide method:

Multiply a by c.
x^2-7x+6

Factor
(x-1)(x-6)

Divide the two factors by the a value and simplify.
(x-1/3)(x-6/3)
(x-1/3)(x-2)

Put any remaining denominators at the beginning of the binomial.
(3x-1)(x-2)

Final anwer: (3x-1)(x-2), Roots= 1/3, 2
