The midpoint of \overline{\text{AB}} AB is M(-1, -2)M(−1,−2). If the coordinates of AA are (1, 3)(1,3), what are the coordinates of BB?

If you would like to find the equivalent expression, you can calculate this using the following steps:

x^3 + 3 * x^2 - x + 2 * x^2 + 6 * x - 2 = x^3 + 3 * x^2 + 2 * x^2 - x + 6 * x - 2 = x^3 + 5 * x^2 + 5 * x - 2

The correct result would be x^3 + 5 * x^2 + 5 * x - 2.
