Question

Ifa polynomial f (x) is divided by x? -16 then remainder is 5x +3, what will be
the remainder when the same polynomial is divided by (x+4)?​

Answer 1

Answer:

By remainder theorem

x+1=0

x=−1

p(x)=x +3x ² −3x−1p(−1)

=(−1) ³ +3(−1) ²−3(−1)−1

=−1+3(1)+3−1

=−1+3+3−1

=6−2

=4

Thus remainder is 4

Answer 2

Answer:

=> x + 1 = 0 [ By Remainder Theorum ].

=> x = -1.

=> p(x) = x + 3x^2 - 3x - 1p ( -1 ).

=> = ( -1 )^3 + 3 ( -1 )^2 - 3 ( -1 ) - 1.

=> - 1 + 3 ( 1 ) + 3 - 1.

=> 1 + 3 +3 - 1.

=> 6 - 2.

=> The remainder is 4.
