0.2 x^{2} + 0.4 x - 0.3 = 0

x = \frac{- 2 + 10}{2}, x = - \frac{2 + 10}{2}

Decimal Notation

x = 0.58113 \dots, x = - 2.58113 \dots

Solution steps

0.2 x^{2} + 0.4 x - 0.3 = 0

Multiply both sides by

10

2 x^{2} + 4 x - 3 = 0

Solve with the quadratic formula

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

4^{2} - 4 \cdot 2 (- 3) = 210

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

Separate the solutions

x_{1} = \frac{- 4 + 2 10}{2 \cdot 2}, x_{2} = \frac{- 4 - 2 10}{2 \cdot 2}

x = \frac{- 4 + 2 10}{2 \cdot 2} : \frac{- 2 + 10}{2}

x = \frac{- 4 - 2 10}{2 \cdot 2} : - \frac{2 + 10}{2}

The solutions to the quadratic equation are:

x = \frac{- 2 + 10}{2}, x = - \frac{2 + 10}{2}

a - 5 \geq - 9

(12 x^{\frac{1}{2}})^{2}

(ab)^{- 2}

x^{4} + 3 x^{3} - 20 x^{2} - 84 x - 80

(3 x - 1)^{2} = 22
