If x = 3 and y = 2, what is the value of 5(x-y)^2 - xy ?  Select the correct option: A) -8 B) -7 C) -1 D) -2 E) -5
x = 3 and y = 2   x-y = 3 - 2=

<output>6</output>
6   Now we apply it in the equation 5(x-y)^2 - xy=5 (1)^2-6   ==&gt;5*1 -6 = 5-6 =-1   Answer : -1
<result>C</result>
If x = 3 and y = 2, what is the value of 5(x-y)^2 - xy ?
