Question

If polynomials x^3+ax^3+3x-5and x^3+x^2-4x+a leave the same reminder when divided by x-2 find the value of a​

Answer 1

Answer:

-5/7

Step-by-step explanation:

when polynomial is divided by x-2 reminder is f(2)

first polynomial remainder is

2^3+a×2^3+3×2-5

=8+8a+6-5 -----A

second polynomial remainder is

2^3+2^2-4×2+a

=8+4-8+a -------B

its given that A=B

9+8a=4+a

5+7a=0

a=-5/7
