Question

(-t^2+5t^2-6t)+(8t2 – 8t)
Answer should be an expanded polynomial in standard form

Answer 1

The answer should be

12t^2 - 14t

Let me know if it’s right.

Answer 2

Explanation:

[ -t² + 5t² - 6t] + [8t² - 8t] = -t² + 5t² - 6t + 8t² - 8t

{bring the like terms together}

= -t² + 5t² + 8t² - 6t - 8t {add/subtract the like terms}

= 12t² - 14t
