If n = –2, then m is equal to 13;
If n = 0, then m is equal to 7;
If n = 1, then m is equal to 4
You forgot to include the options. This might help, though.
There are two expressions which do not match with the written descriptions to ist right.
Those are:
1) (4x - 3)^2 - 1: see that the written description does not square the difference of 4x and 3
2) 3(5x^2 + 14x + 7): see that the written description tells that 5 is added to the square ox x, which is not what the expression shows.
The other 4 expressions match with the written descriptions.
So, you can choose those other 4 expressions.
