Best ResponseYou've already chosen the best response.0(x+2)(2x+3)=6 =x*(2x+3)+2*(2x+3)=6 =(2x^2+3x)+(4x+6)=6 =2x^2+7x+6=6 =2x^2=7x

Best ResponseYou've already chosen the best response.1looks right :) just to finish it off, that means 2x=7, so x will equal 3.5. However, because x does need to have two roots, the second root will be zero, because in the step that Syamantak left off in, we have that 2x^2=7x, so 0 is a solution to that equation as well.
