Question

If p(x)= x³ +4x - 5 is divided by (x- 1) then the remainder is​

Answer 1

Step-by-step explanation:

P(x)=x³+4x-5

when a polynomial of degree n is divided by

a linear polynomial the remainder is always a const.

so by division algorithm

P(x)=(x-1)q(x)+ c

x³+4x-5=(x-1)q(x)+c

when x=1

1³+4-5=(1-1)q(x)+c

0=c

so Remainder is 0 then (x-1) is a factor of P(x)

Answer 2

Hence ,the remainder is 0
