The factors of given polynomial [6$x^{2} - 5xy - 6y^{2}] = (3x+2y)(2x-3y)$
The given polynomial = 6$x^{2}$ - 5$xy$ - 6$y^{2}$ = 6$x^{2}$ - 9$xy$ + $4xy$ - 6$y^{2}$ = $3x(2x-3y) +2y(2x-3y)$ = $(3x+2y)(2x-3y)$ 6$x^{2}$ - 5$xy$ - 6$y^{2}$ is a composite polynomial $(3x+2y)$ and $(2x-3y)$ are prime factors of polynomial.
