Best ResponseYou've already chosen the best response.0if you solve for y: y=23x, so xy=x(23x)=3528

Best ResponseYou've already chosen the best response.0but now we have x^2+23x=3528 so we didn't get anywhere because we still have to come up with factors of 3528 that add up to be 23. Do you know the quadratic formula?
