Mathematics

Answer:

x^2 - (4+13i)^2

Step-by-step explanation:

This product has the form (a-b)(a+b), which is a 'special product' equal to a^2 - b^2. Following this pattern, [x-(4+13i)][x-(4+13i)] = x^2 - (4+13i)^2. The 2nd term could be expanded if desired, but the above result is the most compact one possible.

Note that any number divided by 0 is undefined.

From the problem,

$\frac{87}{0}$

Since 87 is divided by 0, the answer is undefined
