Question

How to find the zeros of the cubic polynomial when only one zero has given?

Answer 1

make a factor of the given zero like if it is given that 3 is a zero of the polynomial then x-3 will be the factor
then divide this factor with the cubic polynomial ,the quotient will be a quadratic polynomial . just solve it by the convenient method and u will get 2 more factors

Answer 2

Answer:

here is your answer mate....

Step-by-step explanation:

• when one zero is given suppose 1 make it a factor of p(X) i.e x-1 is a factor of p (X) .
• then divide the p(X) by x-1
• q(X) is the quadratic equation.
• solve the quadratic equation i.e q(X).
• by middle splitting term or by quadratic formula.
• then 2 zeros are come they are the other two zeros of cubic polynomial include 1 also.

hope it helps you....
