Question

obtain all the zeros of the polynomial 3x^4+6x^3-2x^2-10x-5 if two of its zeros are -1,-1

Answer 1

equation = 3x⁴+6x³-2x²-10x-5

roots are -1,-1

equation of roots = x+1 , x+1

combined equation of roots = (x+1)²

= x²+2x+1

divide the equation given by the combined equation of roots by long division method.

the resultant equation will be 3x²-5

roots of this equation are x = ±√5/3
