please this is my humble request that if u will answer please send photo of that solution​

Answer 1

Step-by-step explanation:

(x+3)(x+3)

=(x+3)^2

=(x)^2+(3)^2+2×x×3

=x^2+9+6x

Answer 2

Answer:

Answer: Hence proved

Step-by-step explanation:

(X+y)^3 = (x+y)(x+y)^2

Open brackets

(X+y)(x^2+2xy+y^2)

X^3 +2yx^2+xy^2 + y^3 + 2xy^2 + yx^2

X^3 + 3yx^2+3xy^2 + y^3
