answer: 0.1,0.85

step-by-step explanation:

you must evaluate the function f first.   division by 0 is undefined. therefore, the composition cannot be evaluated.

let p(x) = - 7.2x + 3 - 2x + 5.6x + 5

now,

6x + 5 = 0

6x = - 5

x = -5/6

using remainder theorem, the remainder when p(x) is divided by 6x + 5 is obtained by calculating p(-5/6).

= 15 + 6 + 3 + (5/3) + 5

= 29 + (5/3)

= 30 2/3

hence, the remainder is 30 2/3.
