Question

2.(A) Verify that 1, -1 and -3 are the zero's of the cubic polynomial x+3x-x-3 and check the relationship between zero's and co-efficient. OR​

Answer 1

Answer:

x+3x-x-3

General form of cubic polynomial of ax3 + bx 2+ cx + d.

a=1, b=3, c=-1, d=-3

Given the zero's :- 1, 3, -1, -3

alpha=1, bita=3, gamma=-1

Alpha +bita+gamma= - [b/a]

(1)+(3)+(-1)=3/1

3=3

RHS=LHS

Answer 2

Step-by-step explanation:

Degree of an equation

The degree of an equation that has not more than one variable in each term is the exponent of the highest power to which that variable is raised in the equation. The degree is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial.
