Question

5.
Use factor theorem to determine whether x + 3 is a factor of
x³ + 2x - 3 or not.​

Answer 1

Step-by-step explanation:

i think it is x^2 not x^3 if it is x^3 then ( x+3) is not a factor of x^3+2x-3

Answer 2

Step-by-step explanation:

x +3 =0

x = 0-3

x= - 3

x³ + 2x - 3

(-3) +2(-3) - 3

-3 - 6 - 3

- 9 - 3

-12

Therefore it is not a factor
