Question

verify that 3,-1,-1/3 are the zeroes of cubic polynomial​

Answer 1

Answer:

Step-by-step explanation:

● Verifying zeroes :-

==================

•••••••••••••••••••••

=> At x = 3 ,

Since p (3) = 0

Hence , 3 is zero of p (x)

••••••••••••••••••••••

=> At x = -1

Since p (-1) = 0

Hence , -1 is zero of p (x)

•••••••••••••••••••••

=> At x = -1/3

Since p (-1/3) = 0

Hence, -1/3 is zero of p (x)

••••••••••••••••••••••

● Verifying relationship between zeroes and coefficients
