2 x^{2} + 9 x - 4 = 0

x = \frac{- 9 + 113}{4}, x = \frac{- 9 - 113}{4}

Decimal Notation

x = 0.40753 \dots, x = - 4.90753 \dots

Solution steps

2 x^{2} + 9 x - 4 = 0

Solve with the quadratic formula

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

9^{2} - 4 \cdot 2 (- 4) = 113

x_{1, 2} = \frac{- 9 \pm 113}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 9 + 113}{2 \cdot 2}, x_{2} = \frac{- 9 - 113}{2 \cdot 2}

x = \frac{- 9 + 113}{2 \cdot 2} : \frac{- 9 + 113}{4}

x = \frac{- 9 - 113}{2 \cdot 2} : \frac{- 9 - 113}{4}

The solutions to the quadratic equation are:

x = \frac{- 9 + 113}{4}, x = \frac{- 9 - 113}{4}

\frac{7}{13} x - 1 > \frac{1}{2}

x^{2} (x - 8) + 15 (x - 8)

x^{2} - 8 x + 15

2.4 = - \frac{t}{4.5}

3 x^{2} - 18 x + 24
