Question

The value of (a + b2) - (a - b2) is

Answer 1

Step-by-step explanation:

(a+b2) - (a-b2)

value=?

First , we know the identity a2-b2=(a=b)(a-b)

here, a= (a+b2)

and   b= (a-b2)

so,  (a+b2) - (a-b2) = (a+b2+a-b2)( a+b2-a-b2)

which is = 2a

Hence , the value of (a + b2) - (a - b2) is 2a.
