Question

obtain all other zeroes o the polynomial x4-5x3+6x2+2x-4 if two of the zeroes are 1+root3 and 1-root3​

Answer 1

Quadratic expression having zeroes

$1 + \sqrt{3} and \: 1 - \sqrt{3}$

is

$\: {x}^{2} - (1 + \sqrt{3} + 1 - \sqrt{3} )x + (1 + \sqrt{3} )(1 - \sqrt{3} )$

${x}^{2} - 2x - 2$

this is a factor to the given expression

Given expression is
