One zero of the polynomialis 2 / 3 . Find the other zeroes

Answer» \bold{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).
