Question

Разложите на множители 5bc + 5ab 4mn - 12pm 14ab2 + 21a²b x²-xy - 2x e) 8x² - 42xy + 32y² f) | -a²b + 5ab² - 6a²b2​

Answer 1

$5bc + 5ab=5b(c+a)$

$4mn - 12pm=4m(n-3p)$

$4ab^2 + 21a^2b =ab(4b+21a)$

$x^2-xy - 2x =x(x-y-2)$

$8x^2 - 42xy + 32y^2=2(4x^2-21xy+16y^2)$

$-a^2b + 5ab^2 - 6a^2b^2​=-ab(a-5b+6ab)$
