If one roots of the equation `x^(2) - mx + n = 0` is twice the other root, then show that `2m^(2) = 9pi`.

If one root of the equation ax^2+bx+c=0 (a!=0) is twice the other, than show that 2b^2=9ac .

If one root of the equation x^2 - px + q = 0 be twice the other, show that 2p^2 = 9q

If one root of the equation 2x^(2) - ax + 64 = 0 is twice that of the other then find the value of a.

One of the roots of the equation x^2 - 6x + k=0 is x = 2. The other root is:

If one root of the equation 2x^2-5x+k=0 be twice the other, find the value of k.

If one root of the equation 2x^(2)-ax+64=0 is twice that of the other find the value of a.

If one root of the equation ix^2-2(i+1)x+(2-i)=0 is 2-i, then the other root is

If one root of the equation x^(3) - 9x^(2) + 26x -24=0 is twice the other. Then, the sum of the cubes of those two roots is

If the roots of the equation lx^(2) +mx +m=0 are in the ratio p:q, then

In the equation x^2-px+q=0 one root is twice of other then prove that 2p^2=9q
