b) Ta có: \(9x^4+8x^2-1=0\)

\(\Leftrightarrow9x^4+9x^2-x^2-1=0\)

\(\Leftrightarrow9x^2\left(x^2+1\right)-\left(x^2+1\right)=0\)

\(\Leftrightarrow\left(x^2+1\right)\left(9x^2-1\right)=0\)

mà \(x^2+1>0\forall x\)

nên \(9x^2-1=0\)

\(\Leftrightarrow9x^2=1\)

\(\Leftrightarrow x^2=\dfrac{1}{9}\)

hay \(x\in\left\{\dfrac{1}{3};-\dfrac{1}{3}\right\}\)

Vậy: \(S=\left\{\dfrac{1}{3};-\dfrac{1}{3}\right\}\)
