Answer:
[tex]3 {x}^{2} {}^{2} - \sqrt{3 { }^{2} } [/tex]
[tex](3x {}^{2} + \sqrt{3} )(3x { }^{2} - \sqrt{3} )[/tex]
Answer:
x=+-√1,+1,-1
Step-by-step explanation:
3(x^4)-3=0
3(x^4-1)=0
x^4-1=0
using identity a^2-b^2=(a+b)(a-b),
(x^2+1)(x^2-1)=0
again using identity a^2-b^2=(a+b)(a-b) for 2nd bracket,
(x^2+1)(x+1)(x-1)=0
x=+-√1,+1,-1
