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

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

Decimal Notation

x = 0.6, x = - 1.25

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 13 \pm 1 3 ^{2} - 4 \cdot 20 ( - 15 )}{2 \cdot 20}

1 3^{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{3}{5}

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

The solutions to the quadratic equation are:

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

3 5^{2} = 6^{2} + x^{2}

f, (f)^{2} + g = x y - 1

x^{2} + 15 x + 26 = 0

x, x^{2} y - 4 y = 6

- 6 x^{2} - 300 = 0
