Question

show that -2/3 and 3/5 are the zeroes of the polynomial 15x^2 +x-6​

Answer 1

solution.... hope this helps you.

Answer 2

Given:

The polynomial 15x² +x-6​

To Find:

-2/3 and 3/5 are the zeroes of the polynomial

Solution:

The zeroes of a polynomial always satisfy the equation.

Here we will check by substituting both the values .

when x = -2/3

15×(-2/3)²+(-2/3)-6 =  (18/3)-6

                             = 0

when x = 3/5

15×(3/5)²+(3/5)-6 = (30/5)-6

                           =0

Hence, -2/3 and 3/5 are the zeroes of the polynomial 15x² +x-6​
