Question

If x=1,y=2 then the value of
(x2-4xy+4y2)=?​

Answer 1

Answer:

9

Step-by-step explanation:

Given: x= 1

y= 2

substitute these value in the equation

x²-4xy+4y²

= (1)²-4×(1)×(2)+4×(2)²

= 1-8+4×4

= 1-8+16

= 1+8

= 9

correct explanation

hope you understand

Answer 2

Answer:

10

Step-by-step explanation:

If x=1 and y=2

then find the value of (x2+4xy+4y2)

= (x2+4xy+4y2)

= x×1+4×1×2+4×2×2

= 2-8+16

= 10

therefore, (x2+4xy+4y2) = 10
