- 2 x^{2} - 7 x + 13 = 0

x = - \frac{7 + 3 17}{4}, x = \frac{3 17 - 7}{4}

Decimal Notation

x = - 4.84232 \dots, x = 1.34232 \dots

Solution steps

- 2 x^{2} - 7 x + 13 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 ( - 2 ) \cdot 13}{2 ( - 2 )}

(- 7)^{2} - 4 (- 2) \cdot 13 = 317

x_{1, 2} = \frac{- ( - 7 ) \pm 3 17}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 3 17}{2 ( - 2 )}, x_{2} = \frac{- ( - 7 ) - 3 17}{2 ( - 2 )}

x = \frac{- ( - 7 ) + 3 17}{2 ( - 2 )} : - \frac{7 + 3 17}{4}

x = \frac{- ( - 7 ) - 3 17}{2 ( - 2 )} : \frac{3 17 - 7}{4}

The solutions to the quadratic equation are:

x = - \frac{7 + 3 17}{4}, x = \frac{3 17 - 7}{4}

x^{2} = 11664

12 x^{2} - 92 x + 130 = 0

6 p^{2} + 7 p - 20 = 0

x^{2} + 6 x = - 201

x^{2} - x + 18 = - 8 x + 8
