x^{2} - 36 = - 9 x

x = 3, x = - 12

Solution steps

x^{2} - 36 = - 9 x

Move

9 x

to the left side

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

Write in the standard form

a x^{2} + b x + c = 0

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

0.3 + 0.08 x - 0.0012 x^{2} = 0

x (x + 6) + 2 x (x + 4) = x^{2} + 8

- 0.2 q^{2} + 80 = 4 q + 20

4 x - 16 = - 2 x^{2}

10 - 2 x^{2} = 0
