Question

factorise: x^4+x^2+1
​

Answer 1

Answer:

x^4+x^2+1

=(x^2)^2+2.x^2.1+(1)^2-x^2

=(x^2+1)^2-(x)^2

=(x^2+x+1)(x^2-x+1)

Answer 2

Given question-:

Factorise

${x}^{4} + {x}^{2} + 1 = 0$

let's try to solve the question

$= > {x}^{4} + {x}^{2} + 1 = 0$

$= > {x}^{2} ( {x}^{2} + 1) + 1 = 0$

$= > ( {x}^{2} + 1) + 1 = 0$

Hope this will help you..

Thank you
