Answer 2

The remainder when x³ + 9x + 5 is divided by x is 5

Given :

x³ + 9x + 5 is divided by x

To find :

The remainder

Solution :

Step 1 of 3 :

Write down the given polynomials

Here it is given that x³ + 9x + 5 is divided by x

Let P(x) = x³ + 9x +5 and g(x) = x

Step 2 of 3 :

Find zero of g(x)

For Zero of g(x) we have

g(x) = 0

⇒ x = 0

So zero of g(x) is 0

Step 3 of 3 :

Find the remainder

By Remainder Theorem the required Remainder when P(x) is Q(x) is

$\sf = P(0)$

$\sf = {( 0)}^{ 3} + (9 \times 0) + 5$

$\sf = 0 + 0 + 5$

$\sf = 5$
