To solve this, we can expand the expression using the distributive property:
((t^2 - 9t)^2 + 22(t^2 - 9t) + 112)= (t^4 - 18t^3 + 81t^2 + 22t^2 - 198t + 112)= t^4 - 18t^3 + 103t^2 - 198t + 112
Therefore, the expanded expression is t^4 - 18t^3 + 103t^2 - 198t + 112.

= (t^4 - 18t^3 + 81t^2 + 22t^2 - 198t + 112)
= t^4 - 18t^3 + 103t^2 - 198t + 112
Therefore, the expanded expression is t^4 - 18t^3 + 103t^2 - 198t + 112.
