Question #2850

factorize-
a[sup]4[/sup]+a[sup]2[/sup]+25

Expert's answer

To factorize this expression we have to solve the following equation:

a^{4}+ a^{2} + 25 = 0

D = 1 - 100 = -99

a^{2} = (-1 + i√99)/2 and a^{2 }= (-1 - i√99)/2

(a^{2} + 1/2 - i√99/2)(a^{2 }+ 1/2 + i√99/2) for further factorization you have to find the square roots of both a^{2} s.

a

D = 1 - 100 = -99
