Hi pupil here's your answer ::
__________________________
It can be factorised by splitting the middle term
so, : 6×3=18 factors of 18= 1. 1×18 but 1+18 is not 11 so find another : 9×2 and 9+2 is also 11
so this equation can be written as ::
=》3x2 + 9xy + 2xy+6 y2
=》3x (x+3y) + 2y (x+3y)
=》(3x+2y) (x+3y)
