18 x^{2} + 17 x - 15 = 0

x = \frac{5}{9}, x = - \frac{3}{2}

Decimal Notation

x = 0.55555 \dots, x = - 1.5

Solution steps

18 x^{2} + 17 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 17 \pm 1 7 ^{2} - 4 \cdot 18 ( - 15 )}{2 \cdot 18}

1 7^{2} - 4 \cdot 18 (- 15) = 37

x_{1, 2} = \frac{- 17 \pm 37}{2 \cdot 18}

Separate the solutions

x_{1} = \frac{- 17 + 37}{2 \cdot 18}, x_{2} = \frac{- 17 - 37}{2 \cdot 18}

x = \frac{- 17 + 37}{2 \cdot 18} : \frac{5}{9}

x = \frac{- 17 - 37}{2 \cdot 18} : - \frac{3}{2}

The solutions to the quadratic equation are:

x = \frac{5}{9}, x = - \frac{3}{2}

190 + 25.699 x^{2} = 1270

6 x^{2} = - 2

6 x^{2} = 20

6 x^{2} = 18

x^{2} + 6 x + 10 = 0
