x^{2} + 3 x - 10 = 8

x = 3, x = - 6

Solution steps

x^{2} + 3 x - 10 = 8

Move

8

to the left side

x^{2} + 3 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot ( - 18 )}{2 \cdot 1}

3^{2} - 4 \cdot 1 \cdot (- 18) = 9

x_{1, 2} = \frac{- 3 \pm 9}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 3 + 9}{2 \cdot 1}, x_{2} = \frac{- 3 - 9}{2 \cdot 1}

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

x = \frac{- 3 - 9}{2 \cdot 1} : - 6

The solutions to the quadratic equation are:

x = 3, x = - 6

9 x^{2} - 6 x - 1 = 0

(x - 6) (x + 5) = 0

2 x - 2 < - 10

3 (x - 2)^{2} - 37 = 20

z^{2} - 18 z + 27 = - 9
