Math--polynomial equation

posted by .

Write a polynomial equation with these roots.
a)-1,2+sqt3,2-sqt3
b)2,5,1

sqt= square root

  • Math--polynomial equation -

    (x+1)(x-2-sqrt 3)(x-2+sqrt 3)=0
    (x+1)( x^2 - 4 x + 1 )=0
    x^3-3x^2-3x+1=0

    (x-2)(x-5)(x-1) = 0
    you multiply this time
