Let's go through each of the questions in the image one by one:

1. Given:

$f(x) = \frac{x^3 - 3x^2 + 1}{x(1-x)}$ And we know: $a^2 + \frac{1}{a^2} = 14$ where $a > 0$.

We need to solve this equation for $a$.

2. Problem:

Solve the quadratic equation: $p^2 - 1 + 2q - q^2 = 0$ This is a quadratic in terms of $q$. You are required to find its roots.

3. Problem:

For the function $f(x^2)$, simplify the expression for $f\left(\frac{1}{x^2}\right)$.

4. Problem:

Show that: $\left(a^2 + \frac{1}{a^2}\right) a^3 = 7241$

Let me solve each of these problems one by one.

1. Solving $a^2 + \frac{1}{a^2} = 14$:

We are given that $a^2 + \frac{1}{a^2} = 14$. To find $a$, we can use the following approach:

1. Square both sides: $\left(a^2 + \frac{1}{a^2}\right)^2 = 14^2 = 196$ Expanding the left-hand side: $a^4 + 2 + \frac{1}{a^4} = 196$ Subtract 2 from both sides: $a^4 + \frac{1}{a^4} = 194$

This gives us the relation for $a^4 + \frac{1}{a^4}$.
