Answer:
The result in standard form is:
Step-by-step explanation:
Given the polynomials
- -5t+ 4t² – t
- 8t² + t
subtracting 8t² + t from -5t+ 4t² – t.
Remove parenthese: (-a) = -a
i.e. - (8t² + t) = 8t² - t
so the expression becomes
grouping the like terms
Add similar elements: 4t² - 8t² = -4t²
Add similar elements: -5t - t - t = -7t
Therefore, the result in standard form is:
