Answer:

Dividend

 =x^4 + 5 x^3 - 3 x - 15

Divisor

=x^3-3

The rule of division of polynomial which is same as division of real numbers states that

Dividend = Divisor × Quotient + Remainder

The division process is shown below.

Quotient = x+5

Remainder =0

Answer: Our required polynomial is given by

x+5

Step-by-step explanation:

Since we have given that

f(x)=x^4+5x^3-3x-15

And

q(x)=x^3-3

Since we know that

Euclid division lemma states that

f(x)=q(x)\times g(x)+r(x)

where,

f(x)\text{ denotes the dividend}\\g(x)\text{ denotes the required polynomial}\\q(x)\text{ denotes the quotient}\\r(x)\text{ denotes the remainder}\\

Now,

x^4+5x^3-3x-15=x^3-3\times g(x)+0

So, our equation becomes

g(x)\\\\=\frac{x^4+5x^3-3x-15}{x^3-3}\\\\=x+5

So, our required polynomial is given by

x+5
