Answer 1

Answer:

a^2+b^2+2ab step are given below

Step-by-step explanation:

(a+b)(a+b)

a(a+b)+b(a+b) Now multiply

=a^2+ab+ab+b^2 Now add same thing together.

=a^2+2ab+b^2.

Answer 2

Hello !!

About the statement, we need expand

(a + b)^2.

(a + b)^2

(a + b)^2 = (a + b) × (a + b)

(a+b)^2 = [(a)(a)] + [(a)(b)] + [(a)(b)] + [(b)(b)]

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

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

Final result : a^2 + 2ab + b^2.

I hope I have collaborated !
