Question

factorize using identitiy : 3x⁴-3​

Answer 1

Answer:

$3 {x}^{2} {}^{2} - \sqrt{3 { }^{2} }$

$(3x {}^{2} + \sqrt{3} )(3x { }^{2} - \sqrt{3} )$

Answer 2

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
