Ответ:

x^4-3x^2+2=0

a=x^2

a^2-3a+2=0

по теореме Виета

a1=2

a2=1

если a=x^2, то

x1= $\sqrt{2}$

x2= $-\sqrt{2}$

x3=-1

x4=1

-3x^4+12x^2-12=0

a=x^2

-3a^2+12a-12=0

D=b^2-4ac=144-4*(-3)*(-12)=0

$a=\frac{-b-\sqrt{D}}{2a}=$ $\frac{-12-0}{-6} =2$

x1= $-\sqrt{2}$

x2= $\sqrt{2}$

3x^4+9x^2-12=0

a=x^2

3a^2+9a-12=0

D=b^2-4ac=81-4*3*(-12)=225

$a=\frac{-b-\sqrt{D}}{2a}=$ $\frac{-9-15}{6}=\frac{-24}{6}=-4$

$a2=\frac{-b+\sqrt{D}}{2a}=$ $\frac{-9+15}{6}=\frac{6}{6}=1$

x1= $-1$

x2= $1$
