Question

zeros of a polynomial X square + 5 x - 24 hour equal or both positive or both negative​

Answer 1

Answer:

Given the zeroes of the quadratic polynomial ax  

2

+bx+c are both negative.

Then the sum of the zeroes be also negative, then

−  

a

b

​  

<0

or,  

a

b

​  

>0.......(1).

And the product of the zeroes is positive then,

a

c

​  

>0.......(2).

F(0)=c>0 ⇒ a>0⇒ b>0

From (1) and (2) it follows that a,b,c all have the same sign.
