Question

if X = 3 and y = -2 then evaluate the following x^2 - 2xy + y^2
plz let me know in detail with understandable steps​

Answer 1

Answer:

25

Step-by-step explanation:

we know that,

(x - y)^2=x^2 - 2xy + y^2

=> x^2 - 2xy + y^2 = (x - y)^2

Now, it is given that,

x = 3 and y = -2

So the value of expression = ( 3 - (-2))^2

= 5^2 = 25
