Question

algebraic identity to prove (a+b)^2=a^2+2ab+b^2​

Answer 1

Answer:

The algebraic expression (a+b)2 is nothing but (a+b) × (a+b). This can be visualized as a square whose sides are (a+b) and the area is (a+b)2. The square with a side of (a + b) can be visualized as four areas of a2, ab, ab, b2. The sum of these areas a2 + ab + ab + b2 gives the area of the square (a+b)2. The area of the square (a+b)2 = a2 + ab + ab + b2 proves the algebraic identity.

Answer 2

Answer:

a+b×a+b = a×a+2ab+b×b
