3x^(2)+7x+2

If x = 1/(2-sqrt3) then find the value of (x^(3) -2x^(2) -7x+2)

If f(x+3)=x^(2)-7x+2, then find the remainderwhen f(x) is divided by (x+1)

If f(x+3)=x^(2)-7x+2 , then find the remainder when f(x) is divided by (x+1) .

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
