5 x^{2} + 6 x + 1.8 = 0

x = - \frac{3}{5}

Decimal Notation

x = - 0.6

Solution steps

5 x^{2} + 6 x + 1.8 = 0

Multiply both sides by

10

50 x^{2} + 60 x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 60 \pm 6 0 ^{2} - 4 \cdot 50 \cdot 18}{2 \cdot 50}

6 0^{2} - 4 \cdot 50 \cdot 18 = 0

x_{1, 2} = \frac{- 60 \pm 0}{2 \cdot 50}

x = \frac{- 60}{2 \cdot 50}

\frac{- 60}{2 \cdot 50} = - \frac{3}{5}

x = - \frac{3}{5}

The solution to the quadratic equation is:

x = - \frac{3}{5}

16 n^{2} - 10 n - 5 = 6 n

4 (3.5) - 2 > 3 (3.5) + 1
