Question

Which statement is true about polynomial 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 after it has been fully simplified?

Answer 1

all I know is that there are 4 terms :^)

Answer 2

Answer:  3t²(2st⁷ - s⁶ - 2t⁵)

Step-by-step explanation:

5s⁶t² + 6st⁹ - 8s⁶t² - 6t⁷     5s⁶t² and - 8s⁶t² are like terms which = -3s⁶t² when combined

=          6st⁹ - 3s⁶t² - 6t⁷      next, factor out the GCF of 3t²

=      3t²(2st⁷ - s⁶ - 2t⁵)
