Maritza saw on the board that the teacher had written   $\left(x-3\right)\left(x+3\right)\ =\ x^{2\ }-9$ . She said, “I see what happened, so that means that   $\left(x-2\right)\left(x+5\right)$  must equal  $x^{2\ }-\ 10$ ." Use complete sentences and show your calculations to explain how you know if Maritza is right or wrong.
