Question

For any two integers a and b, (a + b)2 = a? + b2

Answer 1

Answer:

(a+b)2 = a2 + b2

Step-by-step explanation:

Answer 2

Answer:

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

Step-by-step explanation:

We have been given an incomplete statement $(a+b)^2=a?+b^2$. We are supposed to complete the given statement.

We can see that left side of our given equation represents a perfect square. The right side of equation would be perfect square trinomial.

Let us use perfect square formula to expand our given perfect square as:

$(x+y)^2=x^2+2xy+y^2$

Substitute $x=a$ and $y=b$:

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

Therefore, the complete statement would be $(a+b)^2=a^2+2ab+b^2$.
