0 = 2 q^{2} + 30 q - 200

q = 5, q = - 20

Solution steps

0 = 2 q^{2} + 30 q - 200

Switch sides

2 q^{2} + 30 q - 200 = 0

Solve with the quadratic formula

q_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 2 ( - 200 )}{2 \cdot 2}

3 0^{2} - 4 \cdot 2 (- 200) = 50

q_{1, 2} = \frac{- 30 \pm 50}{2 \cdot 2}

Separate the solutions

q_{1} = \frac{- 30 + 50}{2 \cdot 2}, q_{2} = \frac{- 30 - 50}{2 \cdot 2}

q = \frac{- 30 + 50}{2 \cdot 2} : 5

q = \frac{- 30 - 50}{2 \cdot 2} : - 20

The solutions to the quadratic equation are:

q = 5, q = - 20

48 \cdot 5

\frac{x - 9}{x + 8} \geq 3

4 x^{2} + 0.36 - 0.009 = 0
