x^{2} + 1.6 x + 0.63 = 0

x = - \frac{7}{10}, x = - \frac{9}{10}

Decimal Notation

x = - 0.7, x = - 0.9

Solution steps

x^{2} + 1.6 x + 0.63 = 0

Multiply both sides by

100

100 x^{2} + 160 x + 63 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 160 \pm 16 0 ^{2} - 4 \cdot 100 \cdot 63}{2 \cdot 100}

16 0^{2} - 4 \cdot 100 \cdot 63 = 20

x_{1, 2} = \frac{- 160 \pm 20}{2 \cdot 100}

Separate the solutions

x_{1} = \frac{- 160 + 20}{2 \cdot 100}, x_{2} = \frac{- 160 - 20}{2 \cdot 100}

x = \frac{- 160 + 20}{2 \cdot 100} : - \frac{7}{10}

x = \frac{- 160 - 20}{2 \cdot 100} : - \frac{9}{10}

The solutions to the quadratic equation are:

x = - \frac{7}{10}, x = - \frac{9}{10}

6 x + x^{2} - 13 x - 18 = 0

2 x^{2} + 40 x + 32 = 0

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