5 x^{2} + 280 = - 75 x

x = - 7, x = - 8

Solution steps

5 x^{2} + 280 = - 75 x

Move

75 x

to the left side

5 x^{2} + 280 + 75 x = 0

Write in the standard form

a x^{2} + b x + c = 0

5 x^{2} + 75 x + 280 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 75 \pm 7 5 ^{2} - 4 \cdot 5 \cdot 280}{2 \cdot 5}

7 5^{2} - 4 \cdot 5 \cdot 280 = 5

x_{1, 2} = \frac{- 75 \pm 5}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 75 + 5}{2 \cdot 5}, x_{2} = \frac{- 75 - 5}{2 \cdot 5}

x = \frac{- 75 + 5}{2 \cdot 5} : - 7

x = \frac{- 75 - 5}{2 \cdot 5} : - 8

The solutions to the quadratic equation are:

x = - 7, x = - 8

\frac{5 4}{5 64}

2 + 2 (- 2 + 6 x) = 6 (3 x + 3) - 4 x

x^{2} - 7 x - 18 < 0

- \frac{x - 5}{∣ x - 5 ∣} = 0

2 x^{2} + 5 x + 2 > 0
