Find (−6t3−t2−2t+9)−(−8t3+4t2−4t−5)

Answered by Guest

(−6t3−t2−2t+9)-(-8t3+4t2-4t−5)

 you need to distribute the negative sign for the second equation in ()s.
−6t3−t2−2t+9+8t3-4t2+4t+5
drop the ()s and combine like terms
−6t3−t2−2t+9+8t3-4t2+4t+5
(-6t3+8t3)(-t2-4t2)(-2t+4t)(9+5)
simplifiy
2t3+3t2+2t+14
