Question

If one zero of the quadratic polynomial p(x) = xsquare +4kx minus 25 is negative of the other find the value of k

Answer 1

Hey!

Given polynomial :- p ( x ) = x² + 4kx - 25

Let first Zero be a and second zero be -a ( it is given that one root is negative of other )

• Sum of zeros =
$= \frac{ - coefficient \: of \: x}{coefficient \: of \: \: \: {x}^{2} }$

$a + ( - a) = \frac{ - 4k}{1}$


0 = -4k

0 = K

So, K = 0 !

Answer 2

Answer:

Let one number be a and another number be -a now -4k = a+(-a)

Or, k=0
