Hint: If 2 is one of the roots, then (x2) must be one of the factors. Use long division or synthetic division to find the other factors

so I get 4x^2+4x3 with no remainder, do I break that down and take the factoprs and those become the roots?

4x^2+4x  3 4x^2+6x 2x  3 2x(2x+3)1(2x +3) (2x+3)(2x1) Does that help?

So now check by multiplying (x2)(2x+3)(2x1)

ok so I set each of those equal to 0 to find the roots. Thanks!
