One zero of the polynomialis 2 / 3 . Find the other zeroes |
|
Answer» SINCE, 2/3 is a ZERO of the given polynomial, (3x - 2) is a factor of it. Now, 3x³ + 16x² + 15x - 18 = 3x³ - 2x² + 18x² - 12X + 27x - 18 = x² (3x - 2) + 6x (3x - 2) + 9 (3x - 2) = (3x - 2) (x² + 6x + 9) = (3x - 2) (x + 3)² = (3x - 2) (x + 3) (x + 3) So, all the FACTORS of the given polynomial are (3x - 2), (x + 3) and (x + 3) Therefore, all its ZEROES are 2/3, (- 3) and (- 3). # |
