Mrs. Gretz asked her class to factor f(x) = 2x² + 4x - 70 to find the zeros of the function. Write the name of the student whose statement is correct. KILEY: f(x) has zeros at -7 and 5, because f(x) = 2(x - 7)(x + 5). EDUARDO: f(x) has zeros at 7 and -5, because f(x) = 2(x + 7)(x - 5). REGGIE: f(x) has zeros at -7 and 5, because f(x) = 2(x + 7)(x - 5).
