- x^{2} + 100 x - 2.5 = 0

x = \frac{100 - 3 1110}{2}, x = \frac{100 + 3 1110}{2}

Decimal Notation

x = 0.02500 \dots, x = 99.97499 \dots

Solution steps

- x^{2} + 100 x - 2.5 = 0

Multiply both sides by

10

- 10 x^{2} + 1000 x - 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 1000 \pm 100 0 ^{2} - 4 ( - 10 ) ( - 25 )}{2 ( - 10 )}

100 0^{2} - 4 (- 10) (- 25) = 301110

x_{1, 2} = \frac{- 1000 \pm 30 1110}{2 ( - 10 )}

Separate the solutions

x_{1} = \frac{- 1000 + 30 1110}{2 ( - 10 )}, x_{2} = \frac{- 1000 - 30 1110}{2 ( - 10 )}

x = \frac{- 1000 + 30 1110}{2 ( - 10 )} : \frac{100 - 3 1110}{2}

x = \frac{- 1000 - 30 1110}{2 ( - 10 )} : \frac{100 + 3 1110}{2}

The solutions to the quadratic equation are:

x = \frac{100 - 3 1110}{2}, x = \frac{100 + 3 1110}{2}

2 m^{2} + 9 m - 56 = 0

y = 4 - y^{2}

x, 3 y^{2} + x^{2} - x y = 1

3 t^{2} + 48 = 0

0 = x^{2} - 2 x + 4
