Question

The square of a number y subtracted by 1

translate english phrase to mathematical expression

Answer 1

Answer: y^2 - 1 or y^2 - 2y + 1

Explanation:

I assume you mean do the square of y and not (y - 1).

The squared of y is, well, y^2

So, the answer is y^2 - 1.

However, if you meant (y - 1) ^2 you will end up with y^2 - 2y + 1
