Answer variants:

(6 m + 7 n) ({36 m}^{2} - 42 mn + {49 n}^{2})

2 x (x + 2 y) (x^{2} + 2 xy + {4 y}^{2})

(3 x + 5 y) ({9 x}^{2} - 15 xy + {25 y}^{2})

(3 x + 5 y) ({9 x}^{2} + 15 xy + {25 y}^{2})

2 x (x - 2 y) (x^{2} + 2 xy + {4 y}^{2})

(2 x + 3 y + 4 z) ({4 x}^{2} + {9 y}^{2} + {16 z}^{2} - 6 xy - 12 yz - 8 xz)

(2 x + 3 y + 4 z) ({4 x}^{2} + {9 y}^{2} + {16 z}^{2} - 6 xy + 12 yz + 8 xz)

(6 m - 7 n) ({36 m}^{2} + 42 mn + {49 n}^{2})
