Question

A is a negative odd number.

Choose two words from the list in the box that describe a²
A negative
B positive
Codd
D even

Answer 1

positive and odd

Explanation:

If a is a negative odd number, then a² can't be negative, because a number squared is always positive.

I'll illustrate this with an example.

Let's choose -7 as an example. Instead of a.

-7² = 49

So we see that the result is positive & odd.

So the words that describe a^2 are positive and odd.
