3 x^{2} + 2.25 x - 48.18 = 0

x = \frac{73}{20}, x = - \frac{22}{5}

Solution steps

3 x^{2} + 2.25 x - 48.18 = 0

Multiply both sides by

100

300 x^{2} + 225 x - 4818 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 225 \pm 22 5 ^{2} - 4 \cdot 300 ( - 4818 )}{2 \cdot 300}

22 5^{2} - 4 \cdot 300 (- 4818) = 2415

x_{1, 2} = \frac{- 225 \pm 2415}{2 \cdot 300}

Separate the solutions

x_{1} = \frac{- 225 + 2415}{2 \cdot 300}, x_{2} = \frac{- 225 - 2415}{2 \cdot 300}

x = \frac{- 225 + 2415}{2 \cdot 300} : \frac{73}{20}

x = \frac{- 225 - 2415}{2 \cdot 300} : - \frac{22}{5}

The solutions to the quadratic equation are:

x = \frac{73}{20}, x = - \frac{22}{5}

3 t^{2} - 16 t + 24 = 0

- \frac{121 K - 241920}{756} > 0

\frac{3}{3} - \frac{1}{3}

5 x + 54 \geq 109

\frac{4}{\frac{1}{3}}
