Given the polynomial 21x 4 + 3y - 6x 2 + 34

what polynomial must be subtracted from it to obtain 29x 2 - 7 ?
what polynomial must be added to it to obtain a first degree polynomial?

Suppose a ball is dropped fromca height of 6ft. it bounces back up but time it bounces, it reaches only 7/10 of its pervious height. what is the total of each height that the ball reaches after 5 bounces
