Question

if alpha and beta are the roots of quadratic equations 3xsquare +kx+8=0 and alpha and beta =2/3then find the value of k
$3x^{2} + kx + 8 = 0$
​

Answer 1

Answer:

Step-by-step explanation: as there roots are same therefore D=0

A= 3 , B= k ,c= 8

D= b square -4ac

0= (k )square-4(3)(8)

0=(k) square - 96

Under root 96 = k
