Question

Cat va fi :
a) 3xy-5y=
b)14mn 2(la putere) -7n=
c)3a la puterea a (2)-6a la puterea (3)+18a la puterea a (4)=
d)4a+by+ay+4b=
e)6x+7y+42+xy=
Va rog mult ma poate cineva ajuta?

Answer 1

a) 3xy-5y=y(3x-5)
b)14mn² -7n=7n(2mn-1)
c)3a ²-6a³+18a⁴)=3a²(1-2a+6a²)
d)4a+by+ay+4b=4(a+b)+y(a+b)=(a+b)(4+y)
e)6x+7y+42+xy=6(x+7)+y(x+7)=(x+7)(6+y)

Answer 2

3xminus 5
3a2(1plus3a2plus 12a2
4a(1plus a)plus 4b(yplus1)
