4 x^{2} + 12 x + 9 = 0

x = - \frac{3}{2}

Solution steps

4 x^{2} + 12 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 \cdot 4 \cdot 9}{2 \cdot 4}

1 2^{2} - 4 \cdot 4 \cdot 9 = 0

x_{1, 2} = \frac{- 12 \pm 0}{2 \cdot 4}

x = \frac{- 12}{2 \cdot 4}

\frac{- 12}{2 \cdot 4} = - \frac{3}{2}

x = - \frac{3}{2}

The solution to the quadratic equation is:

x = - \frac{3}{2}

(- \frac{1}{2 7 - x})^{2}

- 9 \leq \frac{13}{4} x - 1 \leq - 1

- \frac{3}{5} + 1

x^{2} + x + 4 \geq 0
