Question

if alpha and beta are the roots of the quadratic equation 3 X square + kx + 8 is equals to zero and Alpha upon beta is equals to 2 upon 3 then find the value of k ​

Answer 1

Step-by-step explanation:

3xsquare+kx+8=0 then substitute first x=2 and the second x=3 then the equation will be

3×2square+3k+8=0

12+3k+8=0

3k= -8-12

3k=-20

k=-20÷3

k=-15
