(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
looks 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.
I have 3 answers which one is the correct one {-2,-3/2}, {-7/2, 0}, {0}
