2 x^{2} + 6 x + 4 = 24

x = 2, x = - 5

Solution steps

2 x^{2} + 6 x + 4 = 24

Move

24

to the left side

2 x^{2} + 6 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 2 ( - 20 )}{2 \cdot 2}

6^{2} - 4 \cdot 2 (- 20) = 14

x_{1, 2} = \frac{- 6 \pm 14}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 6 + 14}{2 \cdot 2}, x_{2} = \frac{- 6 - 14}{2 \cdot 2}

x = \frac{- 6 + 14}{2 \cdot 2} : 2

x = \frac{- 6 - 14}{2 \cdot 2} : - 5

The solutions to the quadratic equation are:

x = 2, x = - 5

9.08 = 0.001 (0.725 x^{2} + 15.417 x + 607.732)

z^{2} - 10 z + 9 = 0

y^{2} - 8 y - 16 = 0

x^{2} - 6 x + 7 = 0

x^{2} - 8 x = 12
