Answer 1

Answer:

a^2+2ab+b^2

hope it helps :)

Answer 2

Answer:

Answer is => a²+b²+2ab

Step-by-step explanation:

$this \: is \: an \: algebraic \: identity \: . \\ \\ (a + b) {}^{2} = (a + b) \times (a + b) \\ (a + b) \times (a + b) = a {}^{2} + ab + ba + b {}^{2} \\ (a + b) \times (a + b) = a {}^{2} + b {}^{2} + 2ab \\ \\ some \: other \: indenties \: are \: .$

(a-b) ² = (a-b) *(a-b)

(a-b) * (a-b) =a²-ab-ba-b²

(a-b) *(a-b) =a²+b²=2ab

(a-b) ²=a²+b²-2ab

And

(a+b) *(a-b) =a²-ab+ba+b²

(a+b)*(a-b) =a²-b²

prove (a+b) ²=a²+b²+2ab in algebra

• ( a+b) ²=(a+b) *(a+b)

= (a*a+a*b) + (b*a+b*b)

= ( a²+ab) + (ba+b²)

=a²+2ab+b²

hence prove.

= ( a+b) ²= a²+b²+2ab

i hope, full help it
