Question

17. Find the value of a for which the polynomial (x*-x-11x2-x+a) is
divisible by (x+3).

I will like who can give answer to me.

Answer 1

Answer:

By Remainder Theron its answer is 69+a

Value of a is -69

Step-by-step explanation:

$(x - x - 11x2 - x + a)$

$( - 3) - ( - 3) - 11( - 3)2 - ( - 3) + a$

$- 3 + 3 + 33 \times 2 + 3 + a$

$0 + 66 + 3 + a$

$69 + a$

Value of a from this polynomial,

$69 + a = 0$

$a = - 69$
