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

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

Decimal Notation

x = 2.5, x = - 0.8

Solution steps

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

Solve with the quadratic formula

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

(- 17)^{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{5}{2}

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

The solutions to the quadratic equation are:

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

∣ - 7 x + 4 ∣ = 18
