Final answer:
Subtract (9t²)/(3t-8)-(64)/(3t-8) by combining the terms over the common denominator and simplifying to get the final answer of 3t + 8.
Step-by-step explanation:
To subtract (9t²)/(3t-8)-(64)/(3t-8), notice that both terms have the same denominator. You can combine them into a single fraction by subtracting the numerators:
(9t² - 64) / (3t - 8)
Reduce this expression to its lowest terms:
- Factor the numerator, which is a difference of squares: (3t + 8)(3t - 8)
- Cancel out the common factors in the numerator and the denominator:
3t + 8
The fraction is now reduced to the lowest terms. The final answer is 3t + 8.'
