x^{2} + 6 x + 9 = 0

x = - 3

Solution steps

x^{2} + 6 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot 9 = 0

x_{1, 2} = \frac{- 6 \pm 0}{2 \cdot 1}

x = \frac{- 6}{2 \cdot 1}

\frac{- 6}{2 \cdot 1} = - 3

x = - 3

The solution to the quadratic equation is:

x = - 3

3 (\frac{5}{6})^{2} - 5 (\frac{5}{6}) + 6

5 x^{2} - 40 x + 75

5 - 3 x \leq - 2

\frac{5 x ^{2} y + 5 x y ^{2}}{x + y}

3 x^{3} - 24
