Answer:

\sqrt{2} , -\sqrt{2}

Step-by-step explanation:

\frac{3x^{2} }{2} =3

3x^{2} = 3*2

3x^{2} =6

3x^{2} -6=0

3(x^{2}-2)=0

x^{2}-2=0

x^{2} -(\sqrt{2} )^{2} =0     ----- use the formula a^{2} -b^{2} =(a+b)(a-b)

(x+\sqrt{2} )(x-\sqrt{2} )=0

(x+\sqrt{2} )=0 \\(x-\sqrt{2} )=0

x = \sqrt{2}

or

x = -\sqrt{2}
