Lindsay tried to reduce the following expression to lowest terms:

What mistake did Lindsay make?

• She excluded x = -3, which doesn't make the denominator equal to zero.

• She excluded x = 3, which doesn't make the denominator in the new expression equal to zero.

• She excluded x = 0, which doesn't make the numerator equal to zero.

• She didn't factor the numerator correctly.
