\[1)\ 6a - 15b = 3 \cdot (2a - 5b)\]

\[2)\ 2a + ab = a \cdot (2 + b)\]

\[3)\ 7am + 7bn = 7 \cdot (am + bn)\]

\[4)\ 4x^{2} - 12xy = 4x \cdot (x - 3y)\]

\[5)\ a^{6} + a^{2} = a^{2} \cdot (a^{4} + 1)\]

\[6)\ 12m^{2}n - 4mn =\]

\[= 4mn \cdot (3m - 1)\]

\[7)\ 2x^{2} - 4x^{3} + 10x^{4} =\]

\[= 2x^{2} \cdot (1 - 2x + 5x^{2})\]

\[8)\ 10a^{3}b^{2} - 15a^{2}b + 25ab^{2} =\]

\[= 5ab \cdot (2a^{2}b - 3a + 5b)\]
