Question

Вынесите общий множитель за скобки
8)15ab^2-6b
9)24a^2y-12ay
10)7a+6ab
11)15xy-10y
12)9ab+21ax

Answer 1

8) 15ab²-6b=3b(5ab-2)
9) 24a²y-12ay=12ay(2a-1)
10) 7a+6ab=a(7+6b)
11) 15xy-10y=5y(3x-2)
12) 9ab+21ax=3a(3b+7x)

Answer 2

8)
$15a {b}^{2} - 6b = 3b(5ab - 2)$
9)
$24 {a}^{2} y - 12ay = 12ay(2a - 1)$
10)
$7a + 6ab = a(7 + 6b)$
11)
$15xy - 10y = 5y(3x - 2)$
12)
$9ab + 21ax = 3a(3b + 7x)$
