Question

10 example of (x+y)² identity​

Answer 1

Answer:

If you already know the (a+b)2 identity is just (a2+2ab+b2), you can replace the a and b with corresponding numbers.

Step-by-step explanation:

e.g: (2+5)2 = (4 + 20 +25) = 49

      a2 + 2ab + b(a+b) = (a+b)2 + ab

Answer 2

(x+y)² = x² + 2xy + y².

If you remember the above algebric identity, then you will be able to solve anytypes of questions related to this topic.

NUMERAL-INCLUDING EXAMPLE

(5+2)² = 5² + (2×5×2) + 2² = 49
