441.Find all the zeros of the polynomial 2x4 + 7x3 – 19x2 – 14x + 30, if two of its zeros are
Since, two zeros are ∴ is a factor of the given polynomial. Now, we divide the given polynomial by x2 – 2. ∴ Now,2x2 + 7x – 15 = 2x2 + 10x –3x – 15 = 2y (x + 5) – 3 (x + 5) = (x + 5) (2x – 3) So. its zeros are given by x = – 5 and x = 3/2 . Hence, the zeros of the given polynomials are : Ans.
