If by X2 you mean X^2, ^2 means squared.
Any number/variable squared means to multiply by itself.

For example, 2^2.

2^2 = 2 x 2, = 4.

5^2 = 5 x 5, = 25.

Now that we've broken down what ^2 means, let's try to square our answers and see if any match.

6^2 = 6 x 6, = 36, this is one. We're looking for squares that are less than 100.
< means less than, > means greater than (reading from left to right).

10^2 = 10 x 10, = 100, this is NOT one, as we're looking for numbers LESS than 100.

13^2 = 13 x 13, = 169. This is NOT one, as we're looking for numbers LESS than 100.

(-5^2)= -25 (-25 if -5^2 was in parenthesis), this is one, as it's less than 100.

(-10^2) = -100, this is one, as it's less than 100.

(-14^2) = -196, this is one, as it's less than 100.

Our final answers are:
6, -5, -10, -14.

I hope this helps!

The correct answer is $90
