Question

Evaluate (4x + y)whole square by suitable identity

Answer 1

Answer:

16x^2 + y^2 + 8xy

Step-by-step explanation:

(4x+y)^2

by using (a+b)^2 formula

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

Here , a = 4x.

b = y

(4x+y)^2 =(4x)^2 + (y)^2 + 2(4x y)

=16x^2 + y^2 + 8 xy

Answer 2

Answer:

16x²+y²+8xy

hope its help you
