Best ResponseYou've already chosen the best response.1Hint: 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

Best ResponseYou've already chosen the best response.0so I get 4x^2+4x3 with no remainder, do I break that down and take the factoprs and those become the roots?

Best ResponseYou've already chosen the best response.14x^2+4x  3 4x^2+6x 2x  3 2x(2x+3)1(2x +3) (2x+3)(2x1) Does that help?
