Question

15 x square - 11 x - 14 show that -1, 3 and 5 by 2 are zeros of the polynomial

Answer 1

Answer:

Since x=7/5, -2/3. Hence -1, 3, 5/2 are zeros of the polynomial

Step-by-step explanation:

15x² - 11x -14 (solving the quadratic equation)

= 15x² - 21x + 10x -14

=  (5x-7) (3x+2)

x= 7/5 , -2/3 (none of the given values match with these values of x, hence, they are values of zero to the given polynomial)
