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.

Ryuto tried to reduce the following expression to lowest terms: What mistake did Ryuto make?

• He didn't exclude x = -3 , which makes the numerator equal to zero.

• He excluded  x = 2, which doesn't make the numerator in the new expression equal to zero.

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

• He didn't factor the numerator correctly.

Simplify 

• (x+7)/(x-4)

• -3/4

• (x+3)/(x+4)

• (x+3)/(x-4)
