4 x^{2} + 15 x + 9 = 0

x = - \frac{3}{4}, x = - 3

Decimal Notation

x = - 0.75, x = - 3

Solution steps

4 x^{2} + 15 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 4 \cdot 9}{2 \cdot 4}

1 5^{2} - 4 \cdot 4 \cdot 9 = 9

x_{1, 2} = \frac{- 15 \pm 9}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 15 + 9}{2 \cdot 4}, x_{2} = \frac{- 15 - 9}{2 \cdot 4}

x = \frac{- 15 + 9}{2 \cdot 4} : - \frac{3}{4}

x = \frac{- 15 - 9}{2 \cdot 4} : - 3

The solutions to the quadratic equation are:

x = - \frac{3}{4}, x = - 3

- 4 x \leq - 52
