x^{2} + 5 x - 166.4 = 0

x = \frac{- 25 + 17265}{10}, x = - \frac{25 + 17265}{10}

Decimal Notation

x = 10.63963 \dots, x = - 15.63963 \dots

Solution steps

x^{2} + 5 x - 166.4 = 0

Multiply both sides by

10

10 x^{2} + 50 x - 1664 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 50 \pm 5 0 ^{2} - 4 \cdot 10 ( - 1664 )}{2 \cdot 10}

5 0^{2} - 4 \cdot 10 (- 1664) = 217265

x_{1, 2} = \frac{- 50 \pm 2 17265}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- 50 + 2 17265}{2 \cdot 10}, x_{2} = \frac{- 50 - 2 17265}{2 \cdot 10}

x = \frac{- 50 + 2 17265}{2 \cdot 10} : \frac{- 25 + 17265}{10}

x = \frac{- 50 - 2 17265}{2 \cdot 10} : - \frac{25 + 17265}{10}

The solutions to the quadratic equation are:

x = \frac{- 25 + 17265}{10}, x = - \frac{25 + 17265}{10}

2 x - 5 - 3 x^{2} = 0

(4 - x)^{2} = 1

y, x^{2} + y^{2} = 6 x y

3 x^{2} + 6 x = 24

3 x^{2} + 168 = 36 x
