2 x^{2} + 6 x = 36

x = 3, x = - 6

Solution steps

2 x^{2} + 6 x = 36

Move

36

to the left side

2 x^{2} + 6 x - 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 2 ( - 36 )}{2 \cdot 2}

6^{2} - 4 \cdot 2 (- 36) = 18

x_{1, 2} = \frac{- 6 \pm 18}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 6 + 18}{2 \cdot 2}, x_{2} = \frac{- 6 - 18}{2 \cdot 2}

x = \frac{- 6 + 18}{2 \cdot 2} : 3

x = \frac{- 6 - 18}{2 \cdot 2} : - 6

The solutions to the quadratic equation are:

x = 3, x = - 6

12 x^{2} + 15 x = 0

(a + 1) x^{2} + (2 a + 1) x - a = 30

x, x^{2} + x - 1 = 0

1.77 \cdot 1 0^{- 6} - 1.77 \cdot 1 0^{- 5} x - x^{2} = 0

\frac{1}{5} (x + 3)^{2} - 2 = 18
