Question

Write the polynomial whose zeroes are 1,-2

Answer 1

Step-by-step explanation:

Given,

The zeroes are - 1 and 2

Sum of zeroes be as - 1

Product of zeroes be as 2

So ,

K[x^2-(sum of zeroes)x+(product of zeroes)] ( since K is constant)

=K[x^2-(-1)x+2]

=K[x^2+1x+2],if k is 1

=1[x^2+1x+2]

Therefore,

Polynomial is ,

=x^2+1x+2
