-a^2+1/3-1/36
a^6-8a^4+16a^2
a^6-8a^4+16a^2
-a^2+1/3a-1/36
=-(a-1/6)^2
a^6-8a^4+16a^2
=a^2(a^4-8a^2+16)
=a^2(a^2-4)2
=a^2(a-2)^2(a+2)^2
1.-a^2+1/3-1/36
=11/36-a^2
=(√11/6+a)(√11/6-a)
2.a^6-8a^4+16a^2
=a^2(a^4-8a^2+16)
=a^2(a^2-4)^2
.-a^2+1/3-1/36
=11/36-a^2
=(√11/6+a)(√11/6-a)
a^6-8a^4+16a^2
=a^2(a^4-8a^2+16)
=a^2(a^2-4)^2
