Question

please solve this question lesson is polynomial ​

Answer 1

Step-by-step explanation:

(VI) Here, the factors of 5 are +/-1 and +/-5.

Using hit and trial, take the factor to be x + 1.

x + 1 = 0

So, x = -1.

Substituting the value of x in the equation,

= (-1)^3 - (3*-1^2) - (9*-1) - 5

= -1 - 3 + 9 - 5

= 0

So, x + 1 is a factor of the equation.

Now, (x^3) - (3x^2) - (9x) - (5) can be divided by (x + 1) to get the factors
