20 x^{2} - 27 x - 14 = 0

x = \frac{7}{4}, x = - \frac{2}{5}

Decimal Notation

x = 1.75, x = - 0.4

Solution steps

20 x^{2} - 27 x - 14 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 27 ) \pm ( - 27 ) ^{2} - 4 \cdot 20 ( - 14 )}{2 \cdot 20}

(- 27)^{2} - 4 \cdot 20 (- 14) = 43

x_{1, 2} = \frac{- ( - 27 ) \pm 43}{2 \cdot 20}

Separate the solutions

x_{1} = \frac{- ( - 27 ) + 43}{2 \cdot 20}, x_{2} = \frac{- ( - 27 ) - 43}{2 \cdot 20}

x = \frac{- ( - 27 ) + 43}{2 \cdot 20} : \frac{7}{4}

x = \frac{- ( - 27 ) - 43}{2 \cdot 20} : - \frac{2}{5}

The solutions to the quadratic equation are:

x = \frac{7}{4}, x = - \frac{2}{5}

4 y^{2} + 20 y = 0

x^{2} + 8.9 x + 18.7 = 0

- 14 x + 21 - 7 x^{2} = 0

x, f = x^{2} + 2 k x + k

- 3 x^{2} + 18 x = - 30
