Answer 2

Answer:

p = 4 and q = ± 12

Step-by-step explanation:

2 is a root of eqn

So ,

3x^2 -p(x +1) = 0

Putting 2 in x :

3 x 2^2 - p (2 + 1) = 0

12 - p(3) = 0

12 -3p = 0

-3 p = -12

p = 4 ___(1)

Now,

px^2 - qx + 9 = 0

4x^2 - qx + 9 = 0

When roots are equal discriminant is 0.

So,

D = b^2 - 4 ac

0 = q^2 - 4 x 4 x 9

q^2 - 144 = 0

q^2 = 144

q = 12 or q = -12
