If the question is answered by the true algebra rule of how you have wrote it, then the answer will be as follows:
7 * 6 = 42 * t = 42t * 7 = 294t * 6 = 1764t * t = 1764t2

It is T(n) = n2 - 2n + 6
Subtract 21 from both sides. If that's + 4t, the answer is (t - 3)(t + 7) and t = 3, -7 If that's - 4t, the answer is (t + 3)(t - 7) and t = -3, 7
The two possible answer are (-7, -6) and (6, 7).
2t-6=3-t 3t-6=3 Add t to both sides 3t=9 Add 6 to both sides t=3 Divide both sides by 3
