Question

Do you proof?
(a+b)²= a²+2ab+b²​

Answer 1

Step-by-step explanation:

let a =1 and b = 2 and now substitute the values which you have taken in the identity. and now solve the L.H.S and the R.H.S. and see that L.H.S is equal to R.H.S. therefore the L.H.S is not equal to R.H.S because the formula is wrong actually the formula is (a+b)²=a²+2ab+b²

Answer 2

Answer:

(a+b)2 =a2+2ab+b2

Step-by-step explanation:

(a+b)2=(a+b)(a+b)

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

=a2+ab+ab+b2

=a2+2ab+b2
