Question

if the equation x^2 +3x+2=0 and x^2 +kx+6=0 have a common root, then find the value of k.

Answer 1

Answer:

Step-by-step explanation:

Let the common root of both the equations be α

Substitute α in place of x and subtract both the equations you get

α=4÷3-k now substitue this value in α²+3α+2 you get a quadratic equation then solve it
