You can put this solution on YOUR website!
All you need to do on this one is to plug the given values into the expression you are given.
\n" ); document.write( ".
\n" ); document.write( "The expression is:
\n" ); document.write( ".
\n" ); document.write( "\"b%5E2+-+2%2Ab%2Ac+%2B+c%5E2\"
\n" ); document.write( ".
\n" ); document.write( "Then let b = 3 and c = -2 so that the expression becomes:
\n" ); document.write( ".
\n" ); document.write( "\"3%5E2-2%2A%283%29%2A%28-2%29%2B%28-2%29%5E2\"
\n" ); document.write( ".
\n" ); document.write( "Term by term this simplifies to:
\n" ); document.write( ".
\n" ); document.write( "\"9+%2B+12+%2B+4+=+25\"\r
\n" ); document.write( "\n" ); document.write( "With the substitution of the given values for b and c the value of the entire expression
\n" ); document.write( "becomes 25. In your list of answer choices this is Answer D.
\n" ); document.write( ".
\n" ); document.write( "I hope this clarifies it for you and you can see how to proceed with problems such as these.
\n" ); document.write( "
\n" );
