x^{2} + 9 x = 36

x = 3, x = - 12

Solution steps

x^{2} + 9 x = 36

Move

36

to the left side

x^{2} + 9 x - 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 1 \cdot ( - 36 )}{2 \cdot 1}

9^{2} - 4 \cdot 1 \cdot (- 36) = 15

x_{1, 2} = \frac{- 9 \pm 15}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 9 + 15}{2 \cdot 1}, x_{2} = \frac{- 9 - 15}{2 \cdot 1}

x = \frac{- 9 + 15}{2 \cdot 1} : 3

x = \frac{- 9 - 15}{2 \cdot 1} : - 12

The solutions to the quadratic equation are:

x = 3, x = - 12

8 + 10 f > 14 - 2 f

\frac{x}{- 4} - 8 \geq - 9

\frac{25}{9} x^{2} - 36

\frac{1}{2} x + \frac{1}{3} x - \frac{1}{5} (x + 2) \leq \frac{1}{10}
