Step-by-step explanation:

α and β are the roots of the equation:

Sum of the roots is:

Product of the roots is:

Solving the following expressions:

(i)

(ii)

If α and β are the roots of the equation ax² + bx + c = 0, where a, b and c are constants such that a ≠ 0, find in terms of a, b and c expressions for :

As, α and β are the roots of the equation ax² + bx + c = 0

We know that :

and

Now, let's solve given values :

Now, by using identity :

Now, by substituting values of :

By using identity :

By using identity :

Now, by substituting values of :

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
