10 x^{2} + 9 x + 2 = 0

x = - \frac{2}{5}, x = - \frac{1}{2}

Decimal

x = - 0.4, x = - 0.5

Solution steps

10 x^{2} + 9 x + 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 10 \cdot 2}{2 \cdot 10}

9^{2} - 4 \cdot 10 \cdot 2 = 1

x_{1, 2} = \frac{- 9 \pm 1}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- 9 + 1}{2 \cdot 10}, x_{2} = \frac{- 9 - 1}{2 \cdot 10}

x = \frac{- 9 + 1}{2 \cdot 10} : - \frac{2}{5}

x = \frac{- 9 - 1}{2 \cdot 10} : - \frac{1}{2}

The solutions to the quadratic equation are:

x = - \frac{2}{5}, x = - \frac{1}{2}

2 W^{2} + 5 W - 63 = 0

x^{2} - 10 x + 16

y^{2} - 6 y - 27 = 0

4 x^{2} - 8 a x + 5 x - 10 a = 0

5 x^{2} - 9 x + 18 = 4 x^{2}
