Find & for which the given quadratic equation 9 – InterviewSolution

1.	Find & for which the given quadratic equation 9
Answer» Given equation : 9x² + 3kx + 4 = 0For real distinct roots discrimanat will be greater than 0So, (3k)² - 4 × 4 × 9 > 09k² > 16×9k² > 16k > √16 = + or - 4 For -4 it does not hold so, k > 4
