Question

What is the product of polynomial 3xcube+5xsquare-7x-27

Answer 1

Step-by-step explanation:

Given,

Let p, q and r are three zeroes of 3x^3 + 5x^2 - 7x - 27

p*q = 3.......(1)

We know,

Product of three zeroes of polynomial = - d/a

Then,

p*q*r = - (-27)/3 = 9......(2)

Put value of p*q from eq(1) in eq(2)

r = 9/3

r = 3

Therefore, third zero is 3
