Question

one of the zero of cubic polynomal a׳+bײ+c×+d is zero,the product of the other two zero is.​

Answer 1

Answer:

The product of the other two zero is c/a .

Step-by-step explanation:

Let , p , q , r are the roots of the equation a׳+bײ+c×+d .

Let , r =0

We know that the sum of the product of the roots of a cubic polinomial expression taken two at a time is (c/a).

Where , c is the coefficient of x and a is the coefficient of ׳.

Now ,

         pq + qr + pr = c/a

     or , pq + 0 + 0 = c/a [ r=0 ]

     or , pq = c/a .

Therefore , the product of the other two zero is c/a .
