The factors of given polynomial [6$x^{2}$ - 7$xy$ - 5$y^{2}$] = $(3x-5y)(2x+y)$
The given polynomial = 6$x^{2}$ - 7xy - 5$y^{2}$ = 6$x^{2}$ - 10xy + 3xy - 5$y^{2}$ = 2x(3x-5y) +y(3x-5y) =(3x-5y)(2x+y). 6$x^{2}$ - 7xy - 5$y^{2}$ is a composite polynomial. (3x+5y) and (2x+y) are prime polynomials which are prime factors of given polynomial.
