Question

20y*2-6y-36

Answer 1

10 y^2 -3 y -18

( 5y + 6 )( 2y - 3 )

solving for y ?????

Answer 2

20y^2 - 6y - 36

Dividing all by "2"

10y^2 - 3y - 18

by using Factorizing method we can split them.

(5y+6)(2y-3) [Note: If you multiply it again, you'll get the previous numbers.]

In first Case: 5y + 6 = (y = -6/5)

Second Case: 2y - 3 = (y = 18/ 3)
