Simplifying Expressions

Question

How would I go about simplifying this?

t² - 5t + 6 / t² - 49 / t² -4t + 4 / t² + 7t

Answer 1

combine like terms

t^2 +2t -39/t^2

there's only one squared term: t^2

2 t terms 7-5 = 2

3 1/t^2 terms: 6-49+4 = -39

think of it as apples + oranges + cucumbers where t^2 is apples, t is oranges and 1/t^2 is cucumbers
