4 x^{2} - 15 x - 25 = 0

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

Decimal Notation

x = 5, x = - 1.25

Solution steps

4 x^{2} - 15 x - 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 4 ( - 25 )}{2 \cdot 4}

(- 15)^{2} - 4 \cdot 4 (- 25) = 25

x_{1, 2} = \frac{- ( - 15 ) \pm 25}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 25}{2 \cdot 4}, x_{2} = \frac{- ( - 15 ) - 25}{2 \cdot 4}

x = \frac{- ( - 15 ) + 25}{2 \cdot 4} : 5

x = \frac{- ( - 15 ) - 25}{2 \cdot 4} : - \frac{5}{4}

The solutions to the quadratic equation are:

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

9 x + 10 = 7 x

\frac{125 - 7}{35 - 5}
