Question

Let f(x) = 16x5 − 48x4 − 8x3 and g(x) = 8x2. Find f of x over g of x.

Answer 1

The correct answer is
2x^3-6x^2-x

Answer 2

It is given in the question that

$f(x) = 16x^5 -48x^4-8x^3 \ and \ g(x) = 8x^2$

And we have to find the value of

$\frac{f(x)}{g(x)}$

Substituting the values of two functions, we will get

$=\frac{16x^5 -48x^4 -8x^3}{8x^2}$

8x^3 is common in the numerator, and on taking it out, we will get

$= \frac{8x^3(2x^2 -6x-1)}{8x^2} = x(2x^2 -6x-1)$

And that's the required answer .
