Question

r(x)=x²+3x.find zero in the polynomial​

Answer 1

Answer:

x=0 or x=-3

Step-by-step explanation:

First we will equate r(x) with zero,

r(x)=0=x²+3x

0=x²+3x

0=x(x+3)

This is possible if x or (x+3) is equal to zero.

So the value of x can be,

x=0 or x+3=0

x=0 or x=-3

The polynomial has two zeroes because its degree is 2. The degree of a polynomial is equal to the number of zeroes of the polynomial.
