X^2-4
Step-by-step explanation:
Let x be our number.
So we square the number because it says 4 less than the square number.
So we have x^2.
Now, we have to take 4 less than that.
So x^2-4 is our answer.
(This can also be factored because it is in the form a^2-b^2)
(This can be rewritten as (x+2) (x-2))
