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

x = \frac{- 9 + 17}{8}, x = \frac{- 9 - 17}{8}

Decimal Notation

x = - 0.60961 \dots, x = - 1.64038 \dots

Solution steps

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

Solve with the quadratic formula

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

9^{2} - 4 \cdot 4 \cdot 4 = 17

x_{1, 2} = \frac{- 9 \pm 17}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 9 + 17}{2 \cdot 4}, x_{2} = \frac{- 9 - 17}{2 \cdot 4}

x = \frac{- 9 + 17}{2 \cdot 4} : \frac{- 9 + 17}{8}

x = \frac{- 9 - 17}{2 \cdot 4} : \frac{- 9 - 17}{8}

The solutions to the quadratic equation are:

x = \frac{- 9 + 17}{8}, x = \frac{- 9 - 17}{8}

(4 + i)^{2}

2 x + 5 + 2 x + 3 x = 2 x + 6

17 x - 16 \leq 52

\frac{3}{4} - 1

6 x^{2} - 11 x - 3 = 0
