Best ResponseYou've already chosen the best response.0To reduce the problem to one of factoring a quadratic, divide the original cubic (2x3x218x+9) by the given linear factor (x+3) using either synthetic division or polynomial long division.

Best ResponseYou've already chosen the best response.0The resulting quadratic (2x27x+3) can be factored directly or by its roots found using the quadratic formula. The roots (r1, r2) can be turned into factors by eliminating fractions from the product 2(xr1)(xr2). The remaining factors are (2x1), (x3). So your final answer will be 2x3x218x+9 = (x+3)(2x1)(x3)
