Question

2 is root of equation x^2+ax+12=0 and the quadratic equation is x^2 +ax+q=0 find q

Answer 1

Answer:

q=-20

Step-by-step explanation:

2 is root of equation x^2+ax+12=0

Thus putting x=2

2²+2*a+12=0

2a=-16

a=8

2 is root of equation  x^2 +ax+q=0 also

so 4+8*2+q=0

q=-1-16=-20

Answer 2

Answer:

q = -20
