20 x^{2} - 13 x - 15 = 0

x = \frac{5}{4}, x = - \frac{3}{5}

Decimal Notation

x = 1.25, x = - 0.6

Solution steps

20 x^{2} - 13 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 20 ( - 15 )}{2 \cdot 20}

(- 13)^{2} - 4 \cdot 20 (- 15) = 37

x_{1, 2} = \frac{- ( - 13 ) \pm 37}{2 \cdot 20}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 37}{2 \cdot 20}, x_{2} = \frac{- ( - 13 ) - 37}{2 \cdot 20}

x = \frac{- ( - 13 ) + 37}{2 \cdot 20} : \frac{5}{4}

x = \frac{- ( - 13 ) - 37}{2 \cdot 20} : - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{5}{4}, x = - \frac{3}{5}

\frac{w}{5} \leq 4
