← Consider the quadratic equation x² - 2(a - 1)x + (2a + 1) = 0, where a is a real number that may take different values. A repeated root counts as two equal roots. Which of the following statements about its roots are correct?For how many integers k are both roots of the quadratic equation x² - kx + k + 2 = 0 integers? (A repeated root counts as both roots, and different values of k are counted once each.) →
