A) find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: 18 b) find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: 0

a)

b)

Step-by-step explanation:

a) Let the required polynomial be p(x).

We have the relation, + p(x) = 18

i.e. p(x) = 18

i.e. p(x) =

b) Let the required polynomial be q(x).

We have the relation, + q(x) = 0

i.e. q(x) = 0

i.e. q(x) =

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
