Question

For the equation 3x^2 + px + 3 = 0, if one of the roots is the square of the other then p
A)-1/3
D)2/3
B)-1
C) 3
​

Answer 1

Answer:

let, the root be k & k²

k*k²=3/3=1

or, k³=1

or, k= 1

k+k²= -p/3

or, 1+1= -p/3

or, p= -6

process is absolutely right, you can totally rely on this . but you may have mistaken to type the equation.
