Question 73022
All you need to do on this one is to plug the given values into the expression you are given.
.
The expression is:
.
{{{b^2 - 2*b*c + c^2}}}
.
Then let b = 3 and c = -2 so that the expression becomes:
.
{{{3^2-2*(3)*(-2)+(-2)^2}}}
.
Term by term this simplifies to:
.
{{{9 + 12 + 4 = 25}}}

With the substitution of the given values for b and c the value of the entire expression
becomes 25. In your list of answer choices this is Answer D.
.
I hope this clarifies it for you and you can see how to proceed with problems such as these.
