x^{2} - x - 21 + x^{2} - 9 = 0

No Solution for x \in R

Solution steps

x^{2} - x - 21 + x^{2} - 9 = 0

Find positive and negative intervals

x \leq \frac{- 85 + 1}{2}, \frac{- 85 + 1}{2} < x \leq - 3, - 3 < x < 3, 3 \leq x < \frac{85 + 1}{2}, x \geq \frac{85 + 1}{2}

Solve the inequality for each interval

No Solution for x \in R

4 - x^{2} = 0

x, VV - 2 \cdot G \cdot R - K V \frac{V}{M} = x^{2} - K \cdot \frac{x ^{2}}{M} - 2 \cdot K V \frac{x}{M}

(\frac{81}{16})^{\frac{1}{4}}
