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

x = - 5 + 210, x = - 5 - 210

Decimal Notation

x = 1.32455 \dots, x = - 11.32455 \dots

Solution steps

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

Solve with the quadratic formula

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

1 0^{2} - 4 \cdot 1 \cdot (- 15) = 410

x_{1, 2} = \frac{- 10 \pm 4 10}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 4 10}{2 \cdot 1}, x_{2} = \frac{- 10 - 4 10}{2 \cdot 1}

x = \frac{- 10 + 4 10}{2 \cdot 1} : - 5 + 210

x = \frac{- 10 - 4 10}{2 \cdot 1} : - 5 - 210

The solutions to the quadratic equation are:

x = - 5 + 210, x = - 5 - 210

∣ 1 + 6 n ∣ < 23

∣ 2 x + 6 ∣ = ∣ x - 2 ∣

\frac{5 x}{2} - x = \frac{x}{6} - \frac{16}{3}

(x + 1) (x + 2) \leq 9

(\frac{12}{13})^{2}
