Question

find (4x-y)^2 using algebric identities


ans pls it's urgent​

Answer 1

Answer:

8x^2 - 8xy +y^2

Step-by-step explanation:

(4x-y)^2

[(a-b)^2 = a^2 -2ab +b^2]

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

8x^2 - 8xy +y^2

Answer 2

Answer:

16x²+y²–8xy

Step-by-step explanation:

(a–b)²=a²+b²–2ab

a=4x

b=y

(4x–y)²=(4x)²+(y)²–(2×4x×y)

= 16x²+y²–8xy
