If two roots of the equation x^(3)-px^(2)+qx-r=0 are equal in magnitude but opposite in sign,then:

If two roots of the equation x^3 - px^2 + qx - r = 0 are equal in magnitude but opposite in sign, then:

find the condition that x^3 -px^2 +qx -r=0 may have two roots equal in magniude but of opposite sign

find the condition that x^3 -px^2 +qx -r=0 may have two roots equal in magniude but of opposite sign

If (a)/(k),a, ak are the roots of x^(3)-px^(2)+qx-r=0 then a=

If the roots of the equation px^(2)+qx+r=0(pne0) be equal, then q=2sqrt(pr) .

If the roots of the equation q^(2)x^(2)+p^(2)x+r^(2)=0 are the squares of the roots of the equation qx^(2)+px+r=0 , are the squares of the roots of the equation qx^(2)+px+r=0 , then q, p, r are in:

If alpha, beta are the roots of quadratic equation x^(2)+px+q=0 and gamma, delta are the roots of x^(2)=px+r=0, then (alpha-gamma).(alpha-delta) is equal to

If alpha, beta, gamma are the roots of the equatiion x^(3)-px^(2)+qx-r=0 find (i) sumα^(2) (ii) sumalpha^(2) beta
