Detailed Solution

We are asked to divide the polynomial p(x) =

x^{3}

− 3

x^{2}

+ 5x – 3 with the polynomial g(x) =

x^{2}

− 2
We need to find the quotient and remainder for this division.
So, now let us divide the given polynomials.
x - 3

x^{2}

– 2)

\underset{̲}{x^{3} - 3 x^{2} + 5 x - 3}

x^{3} - 2 x

\underset{̲}{- 3 x^{2} + 7 x - 3}

- 3 x^{2} + 6

\underset{̲}{7 x - 9}

Now we need to divide 7x−9 with x2 − 2. But the first term in 7x−9, that is 7x. We can see that degree of the obtained polynomial, that is 7x − 2, is less than the degree of the divisor. So, we cannot divide it.
So, it is the remainder of the above division.
So, from the above we get the quotient as x−3 and the remainder as 7x−9.
Hence the answer is Quotient = x − 3, Remainder = 7x − 9.
So, option (1) is correct.
