Question

Verify that 2,-1,- are the zeroes of the polynomial p(x)=2x-5x2-11x-3. Find the relationship between
zeroes and coefficients.​

Answer 1

Answer:

first put the value of x=2 & -1

if p(x)=0 then yes 2 & -1 are zeros of p(x)

for relationship between zeros and coefficient:

product of zeroes and sum of zeroes
