Factorization ......help neededdddd plzpzlzpzlzpzlpzlzpzl

(vi) 81a^2 – 18ab + b^2
(vii) 7x^3 – 14x^2 + 7x
(viii) 3a^2bx + 3a^2by – 3ab^2x – 3ab^2y
(ix) m^2 – m - 30
(x) y^2 + 7y + 10

plzpzlpzlzpzlz answer correctly n all of them plzpzlpzlzpzlzpzlzplzpz

(vi) 81a^2 – 18ab + b^2
=81a^2-9ab-9ab+b^2
=9a(9a-b)-b(9a-b)
=(9a-b)^2

(vii) 7x^3 – 14x^2 + 7x
7x(x^2+2x+1)
7x(x^2+x+x+1)
7x(x(x+1)+1(x+1))
7x(x+1)(x+1)
7x(x+1)^2

(viii) 3a^2bx + 3a^2by –
3ab^2x – 3ab^2y
3ab(ax+ay-bx-by)
3ab(a(x+y)-(x+y))
3ab(a-1)(x+y)

(ix) m^2 – m - 30
m^2-5m+6m-30
m(m-5)-6(m-5)
(m-6)(m-5)

(x) y^2 + 7y + 10
y^2+5y+2y+10
y(y+5)+2(y+5)
(y+2)(y+5)


Hope it helps

This person asks for answers for all his/her homework questions and doesn't even choose a best answer. He/she also answers questions with one period or ".......". The person has very, very bad grammar with his/her "plzplzplzplzplz" and other stuff. Report and move on.

6) (9a-b)^2

7) 7x(x^2-2x+1)

=7x(x-1)^2
8) 3a^2b(x+y)-3ab^2(x+y)
=(x+y)(3a^2b-3ab^2)
=3ab(x+y)(a+b)
9)(m-6)(m+5)
10)(y+5)(y+2)


do your home work yourself.do not depend on others.

Don't take the easy way out.

Do your own homework. Help is one thing, but 10 problems (over 2 posts) is rediculous.
