Answer 1

Step-by-step explanation:

this is all I can do thanks mark like and follow if you like

Answer 2

Step-by-step explanation:

1)4ab+2mb+ 4an+2mn

= 2b(2a+m)+2n(2a+m)

=(2a+m)(2b+2n)

2)x³+7x²-x-7

=x³-x+7x²- 7

=x(x²-1)+7(x²-7)

=(x²-1)(x+7)

3)6x³-5x+18x²-15

=6x³+18x²-5x-15

=6x²(x+3)-5(x+3)

=(x+3)(6x²-5)

4)n²+8mp-2np-4mn

=n²-2np+8mp-4mn

=n(n-2p)+4m(2p-n)

=n(n-2p)-4m(n-2p)

=(n-2p)(n-4m)

5)mx+nx+my+ny

=x(m+n)+y(m+n)

=(m+n)(x+y)
