Then the position of CoM will keep increasing by 1m every second from the origin, but ACTUALLY it will still always lie at the geometrical centre of the ball.

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). # |
