Question 421102: Factor out 15p^2+xy+6y^2

You can put this solution on YOUR website!
Maybe this must be 15x%5E2%2Bxy-6y%5E2...Or something else...
I shall write a solution for this.
I shall find two numbers with product -90 because 15%2A%28-6%29=90 and and sum 1...I must have -9 and 10.
That is:
15x%5E2%2B10xy-9xy-6y%5E2=
5x%283x%2B2y%29-3y%283x%2B2y%29=
%283x%2B2y%29%285x-3y%29
