Question

: Verify wether the following are zeroes of
Polynomial indicated against then.
P(x)=x²-x-2 ; x= -1,2
​

Answer 1

Answer:

If zeros are given,

• First, you should find the sum of zeros and products of zeros.

• Second, you should substitute them in the formula given below:-

K{x^2-(sum of zeros)X+(product of zeros)}

• Now, you can form a polynomial.

Answer 2

Answer:

putting -1 at place of x

=1+1-2

=0

so -1 is zero of polynomial verified

putting 2 at place of x

=4-2-2

= 0

so 2 is also zero of polynomial verified
