factor a^4+2a^2+9

Solution

factor

a^{4} + 2 a^{2} + 9

Solution

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

Solution steps

a^{4} + 2 a^{2} + 9

Add and subtract

4 a^{2}

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

Factor

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

= (a^{2} + 3)^{2} - 4 a^{2}

Factor

(a^{2} + 3)^{2} - 4 a^{2} : (a^{2} + 3 + 2 a) (a^{2} + 3 - 2 a)

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