It looks like the image contains a list of algebraic expressions. I will help break down and simplify these terms. Let's go through them:

1. $9a^2 - 6a^2$
2. $16x^3 - 4x^2$
3. $a^m - a^m$
4. $2z^2b + 4ab - 10z^3b$
5. $14acd - 7cd + 2cd^2$
6. $3a^2 - 6t + 9a$
7. $8x^4 + 2z^2t^2 - 6q^2t^4$
8. $5x^2y^2 - 7x^y - 20xyz$

Let me know if you'd like further clarification on any of these! I can also guide you through solving or simplifying them.

Would you like me to simplify or explain any specific expressions? Let me know.

Here are five questions to expand on:

1. Would you like to know how to factor the expressions?
2. Do you need help with polynomial division or other operations on these terms?
3. Would you like a deeper explanation of the laws of exponents used here?
4. Are you working on these in a specific mathematical context, such as calculus or algebra?
5. Should I help solve for a variable in any of the expressions?

Tip: When simplifying algebraic expressions, look for like terms (terms with the same variable and exponent) that can be combined to reduce the expression.
