Question

find the remainder using remainder theorem when 3x³- 7x²+7x+11+4 is divided by x+1

Answer 1

HELLO.....FRIEND!!

THE ANSWER IS HERE,

$let \: p(x) \: = \: 3 {x}^{3} - 7 {x}^{2} + 7x + 11 + 4$

According to remainder theorem,

p (x) is divided by x+1 .

So, the remainder will be p (-1).

$= > \: 3( { - 1})^{3} - 7( { - 1})^{2} + 7( - 1) + 15$

$= > \: - 3 - 7 - 7 + 15$

$= > \: - 2$

So, the remainder will be -2 .
