factor a^4-7a^2+1

Solution

factor

a^{4} - 7 a^{2} + 1

Solution

(a^{2} + 1 + 3 a) (a^{2} + 1 - 3 a)

Solution steps

a^{4} - 7 a^{2} + 1

Add and subtract

9 a^{2}

= a^{4} + 2 a^{2} + 1 - 9 a^{2}

Factor

a^{4} + 2 a^{2} + 1 : (a^{2} + 1)^{2}

= (a^{2} + 1)^{2} - 9 a^{2}

Factor

(a^{2} + 1)^{2} - 9 a^{2} : (a^{2} + 1 + 3 a) (a^{2} + 1 - 3 a)

= (a^{2} + 1 + 3 a) (a^{2} + 1 - 3 a)
