Question

The sum and the product of the zeroes of the polynomial f(x)=42-27x+3k² are equal.find the value(s) of k.

Answer 1

Answer:

Step-by-step explanation:

given , sum of 0s = product of 0s

= -b/a = c/a

dividing both sides by a,

-b =c

27=3k2

k2=9

k=3

________________________________________________

given:::

α+β=αβ

-b/a+c/a

-b=c

-(-27)=3k2

27=3k2

k2= 27/3

k2= 9

k= 3
