Question 222115

OK, ZACH, GOOD WORK!!!!!!!!!!!!! I GOT THE SAME THING THAT YOU GOT EXCEPT I GOT "-2640" AND YOU GOT "+2640".  THERE'S NOTHING IN THE RULE BOOK THAT SEZ IT HAS TO DIVIDE EVENLY SO JUST GO AHEAD AT SOLVE IT USING THE QUADRATIC FORMULA.

(2x+120)(2x+53)=9000
4x^2+106x+240x+6360=9000
4x^2+346x-2640=0  divide each term by 2
2x^2+173x-1320=0  quadratic in standard form;  solve using the quadratic formula


Hope this helps---=taylor
