Solve by using Quadratic Formula

please message ,correcting the  question...

i think something is wrong in the question, i think the equation is 

(3y-1)(y-1) = (5y - 3)(2y - 3)

i will solve this .....

(3y + 1)(y-1) = (5y - 3)(2y - 3)

3y^2 - 3y + y - 1 = 10 y^2 - 15y - 6y +9

7y ^2 - 19 y +10 = 0

then apply quadratic formula,

      y = - b + or - √(b^2 - 4 a c) / 2a

            = (19  + or - √ (361 - 4* 7*10))/2* 7

             = (19 + 9 )/14   or (19 -9)/14

            = 2 or 5/ 7............................

ANSWER IS                  y =  2  or    5/7..........


hope you understood...........please message if you have any doubts....thank you
