Step-by-step explanation:
given equation
3x2+2px+2q=0
(put the value of x=2)
3x4+2px2+2q=0
12+4p+2q=0
4p+2q=-12----------------(1)
3x2+2px+2q=0
(put the value of x=3)
3x9+2px3+2q=0
27+6p+2q=0
6p+2q=-27-------------(2)
4p+2q=-6------(1)
6p+2q=-27------(2)
equation first and second solve it
-2p=19
p=-19/2
put the value of equation in first
4x(-19/2/+2q=-6
2x(-19) +2q=-6
-38+2q=-6
2q=-6+38
2q=32
q=32/2
q=16
the value of p=-19/2 and q=16
that is correct answer.
all the best.
