12x+(3x-1)(3x+1)+4x^2 < 4x(3x+3)(1+3x)(1+3x)
You asked:
Solve the inequality \( 12 x + \left(3 x - 1\right) \cdot \left(3 x + 1\right) + 4 {x}^{2} < 4 \cdot x\left( 3 x + 3 \right) \cdot \left(1 + 3 x\right) \cdot \left(1 + 3 x\right) \) for the variable \(x\).
MathBot Answer:
\[x < -1 \wedge x > - \frac{\sqrt[3]{4 \sqrt{281} + 97}}{18} - \frac{2}{9} - \frac{17}{18 \sqrt[3]{4 \sqrt{281} + 97}}\]
