You can put this solution on YOUR website! All you need to do is substitute the given value for x into the expression and then do the arithmetic.
If you meant , then evaluate , that means you need to evaluate:
Apply FOIL:
LCD is 42, so:
Since 169 (13 * 13) and 42 (2 * 3 * 7) have no common factors, this is reduced to lowest terms.
On the other hand, if you meant: , then evaluate , that means you need to evaluate:
Apply FOIL:
LCD is 294, so:
Since 3025 (5 * 5 * 11 * 11) and 294 (2 * 3 * 7 * 7) have no common factors, this is reduced to lowest terms.
