20 x^{2} + 7 x - 3 = 0

x = \frac{1}{4}, x = - \frac{3}{5}

Decimal Notation

x = 0.25, x = - 0.6

Solution steps

20 x^{2} + 7 x - 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 20 ( - 3 )}{2 \cdot 20}

7^{2} - 4 \cdot 20 (- 3) = 17

x_{1, 2} = \frac{- 7 \pm 17}{2 \cdot 20}

Separate the solutions

x_{1} = \frac{- 7 + 17}{2 \cdot 20}, x_{2} = \frac{- 7 - 17}{2 \cdot 20}

x = \frac{- 7 + 17}{2 \cdot 20} : \frac{1}{4}

x = \frac{- 7 - 17}{2 \cdot 20} : - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{1}{4}, x = - \frac{3}{5}

12 x^{2} + x - 6 = 0

9 (2 m - 3)^{2} + 8 = 449
