Answer 2

Answer:

5.(p+q+3) ^2

(a+b+c)^2=a^2+b^2+c^2+2ab+2bc+2ca

=p^2+q^2+3^2+2(p)(q)+2(q)(3)+2(3)(p)

=p^2+q^2+9+2pq+6q+6p

=p^2+q^2+2pq+3(2p+2q+3)

6.54x^3+250y^3

2(27x^3-125y^3)

2((3x)^3-(5y)^3)

a^3-b^3=(a-b)(a^2+ab+b^2)

2(3x-5y)((3x)^2+(3x)(5y)+(5y)^2)

2(3x-5y)(9x^2+15xy+25y^2)

Hope it helps you!!!!
