Question

Form an equation whose roots are the cubes of the roots of the equation x2+mx+n=0.​

Answer 1

Answer:

m=6

Step-by-step explanation:

Given, x^2 +mx +c=0

And, as per question, there only one possible value for x ie. -3

We have,

x=-3

Or, x+3 =0

Squaring both side we get,

Or, x^2 + 6x + 9 =0

Which has to be equal to the above given expression for the single provided root.

So, comparing both equation, we get ,

m = 6
