Question

if one of the roots of the equation X2+6x+k=0 is 4, the other root is -10. Is it true or false?​

Answer 1

Answer:

The answer depends on the value of k

Step-by-step explanation:

Let the equation be ax²+bx+c then

sum of roots= -b/a

product of roots= c/a

Here, the equation is x²+6x+k=0

sum of roots (4+(-10))= -(6)/1 = 6

product of roots(4*(-10))= (-40)/1=40

So if k=40 only then the statement holds true
