If `alpha, beta, gamma, delta` are the roots of `5x^4 - 9x^3 + 2x^2 - 15x + 20 = 0,` then the equation whose roots are `-alpha, -beta, -gamma, -delta` is

If alpha,beta,gamma,delta are the roots of 3x^(4)-8x^(3)+x^(2)-10x+5=0, then the equation whose roots are -alpha,-beta,-gamma,-delta is

If alpha, beta , gamma, delta are the roots of the equation x^4+x^2+1=0 then the equation whose roots are alpha^2, beta^2, gamma^2, delta^2 is

if alpha,beta,gamma are the roots of x^(3)-x^(2)+7x+2=0, then the equation whose roots are -alpha,-beta,-gamma is

If alpha, beta, gamma and delta are the roots of the equation x ^(4) -bx -3 =0, then an equation whose roots are (alpha +beta+gamma)/(delta^(2)), (alpha +beta+delta)/(gamma^(2)), (alpha +delta+gamma)/(beta^(2)), and (delta +beta+gamma)/(alpha^(2)), is:
