f ( x ) : d ( x ) =\((x^{4} + 4 x^{3} + 6 x^{2} + 4x + 5 ) : ( x^{2} + 1 ) =\)
= x² + 4 x + 5
Answer: 
B ) f ( x ) = ( x² + 1 ) ( x² + 4 x + 5 )

Answer:

Option B is correct.

Step-by-step explanation:

We given with two polynomials.

\(f(x)=x^4+4x^3+6x^2+4x+5\)

\(d(x)=x^2+1\)

We have to check which given statement is correct.

For this divide f(x) by d(x)

Division is shown in pic.

After division we get,

Quotient = x² + 4x + 5

Remainder = 0

If, a is dividend , b is divisor , q is quotient and r is remainder ,

then by division algorthium it can be written as ,

a = bq + r

⇒ f(x) = ( x² + 1 )( x² + 4x + 5 ) + 0

f(x) = ( x² + 1 )( x² + 4x + 5 )

Therefore, Option B is correct.
