factor x^4+5x^2+9

Solution

factor

x^{4} + 5 x^{2} + 9

Solution

(x^{2} + x + 3) (x^{2} - x + 3)

Solution steps

x^{4} + 5 x^{2} + 9

Add and subtract

x^{2}

= x^{4} + 6 x^{2} + 9 - x^{2}

Factor

x^{4} + 6 x^{2} + 9 : (x^{2} + 3)^{2}

= (x^{2} + 3)^{2} - x^{2}

Factor

(x^{2} + 3)^{2} - x^{2} : (x^{2} + 3 + x) (x^{2} + 3 - x)

= (x^{2} + 3 + x) (x^{2} + 3 - x)

= (x^{2} + x + 3) (x^{2} - x + 3)
