Question

how do i solve this math problem 30w^2+19w-63?

Answer 1

30w^2+19w-63

        - 19 +/- sqrt( 19^2- 4*30*(- 63))

w = ------------------------------------------

                         2*30

         - 19 +/- sqrt 7921           - 19+/- 89

w =  --------------------------- =  -------------------

                     60                            60

w =( - 19 +89)/60 =  70/60 =  7/6 and

w = ( - 19 - 89)/60 = - 108/60 = -  9/5
