10 x^{2} + 17 x - 20 = 0

x = \frac{4}{5}, x = - \frac{5}{2}

Decimal Notation

x = 0.8, x = - 2.5

Solution steps

10 x^{2} + 17 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 17 \pm 1 7 ^{2} - 4 \cdot 10 ( - 20 )}{2 \cdot 10}

1 7^{2} - 4 \cdot 10 (- 20) = 33

x_{1, 2} = \frac{- 17 \pm 33}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- 17 + 33}{2 \cdot 10}, x_{2} = \frac{- 17 - 33}{2 \cdot 10}

x = \frac{- 17 + 33}{2 \cdot 10} : \frac{4}{5}

x = \frac{- 17 - 33}{2 \cdot 10} : - \frac{5}{2}

The solutions to the quadratic equation are:

x = \frac{4}{5}, x = - \frac{5}{2}

3 x^{3} y^{2} + 9 x^{2} y^{2} - 18 x y^{2}

r^{2} - 24 r + 144 = 0

∣ (1 + i) (2 - i) ∣

\frac{7 y}{8} - \frac{3 y}{5} = \frac{11}{10}

4 x < - 8
