Answer: -5 and 5
Step-by-step explanation: When we talk about excluded values, we mean the values that would not be a solution to the equation.
If we had an answer that made a denominator equal to 0, that would be an excluded value since we can't divide by 0.
To find these values, set each denominator equal to 0, solve for the equation, and you will find the excluded values.
So set t + 5 = 0, t - 5 = 0, and t² - 25 = 0.
You should be able to solve these equations and you will get the answers of t = -5, 5, -5, and 5.
This means that -5 and 5 are the excluded values.
