2 x^{2} - 15 x + 9 = 0

x = \frac{15 + 3 17}{4}, x = \frac{15 - 3 17}{4}

Decimal Notation

x = 6.84232 \dots, x = 0.65767 \dots

Solution steps

2 x^{2} - 15 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 2 \cdot 9}{2 \cdot 2}

(- 15)^{2} - 4 \cdot 2 \cdot 9 = 317

x_{1, 2} = \frac{- ( - 15 ) \pm 3 17}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 3 17}{2 \cdot 2}, x_{2} = \frac{- ( - 15 ) - 3 17}{2 \cdot 2}

x = \frac{- ( - 15 ) + 3 17}{2 \cdot 2} : \frac{15 + 3 17}{4}

x = \frac{- ( - 15 ) - 3 17}{2 \cdot 2} : \frac{15 - 3 17}{4}

The solutions to the quadratic equation are:

x = \frac{15 + 3 17}{4}, x = \frac{15 - 3 17}{4}

2 x^{2} + 12 x = 26

y, 2 x y^{2} + 4 = 2 (3 - x^{2} y) y

- 16 t^{2} + 80 t + 50 = 0

x^{2} - x - 12 = 0

2 b^{2} + 4 b - 126 = 0
