Question

prove that the zeros of a quadratic polynomial x^2 +X+K where K is not equal to zero?​

Answer 1

Given:-

Zero of a quadratic polynomial

$\sf {x}^{2} + x + k$

where k is not equal to zero.

To Prove:-

The zeros of this polynomial can't be positive.

If we put k as 5 and solve it ,we get x as -1.38 and -3.61.

So, if we put negative such as -3,then root will be both positive and negative.
