- x^{2} + 10 x - 15 = 0

x = 5 - 10, x = 5 + 10

Decimal Notation

x = 1.83772 \dots, x = 8.16227 \dots

Solution steps

- x^{2} + 10 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 ( - 1 ) ( - 15 )}{2 ( - 1 )}

1 0^{2} - 4 (- 1) (- 15) = 210

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

Separate the solutions

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

x = \frac{- 10 + 2 10}{2 ( - 1 )} : 5 - 10

x = \frac{- 10 - 2 10}{2 ( - 1 )} : 5 + 10

The solutions to the quadratic equation are:

x = 5 - 10, x = 5 + 10

8 x^{2} + x - 1 = 0

\frac{2}{4} + \frac{3}{4} + 1

10 x^{2} + 7 x - 12

\frac{7 - 3 x}{2} \leq 1

2 x^{2} - x - 28
