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
= -b/a = c/a
dividing both sides by a,
-b =c
27=3k2
k2=9
k=3

Answer:
k = 3
Step-by-step explanation:
given:
sum of zeroes= alfa+ beta = -b/a
product of zeroes= (alfa.beta) = c/a
according to the question,
= 27/4 =. 3k²/4
=. 27= 3k²
=. k²= 9
=. k=√ 9
=. k=3
