If one factor of x squared plus 2 x minus 24 is open paren x plus 6 close paren , what is the other factor?

Factor the quadratic by finding two numbers whose product is −24 and whose sum is 2. Those numbers are 6 and −4, so x² + 2x − 24 = (x + 6)(x − 4). Since one factor is (x + 6), the other factor is (x − 4), choice A.
