Question

solve using Identies 1) (2x +y)2​

Answer 1

Answer:

4x^2 + y^2 + 4xy

Step-by-step explanation:

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

(2x+y)^2= (2x)2 + (y)2 + 2×2x×y

= 4x^2 + y^2 + 4xy or 4x2 + y2 + 4xy

Answer 2

HOPE THIS HELPS YOU:

In the given problem, we have to evaluate expressions

by using identitiesWe have been given (2x + y) (2x -y)

We shall use the identity (a +6)(a - b) = a -b

Here a = 2x, b = y

By applying identity we get (2x + y)(2x - y) = (2x)^2 - (y)^2 = (2x x 2x) - (y x y) = 4x^2 - y^2

Hence the value of (2x + y)(2x -y) is 4x^2 - y^2
