2 x^{2} + 2 x - 144 = 0

x = 8, x = - 9

Solution steps

2 x^{2} + 2 x - 144 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 2 ( - 144 )}{2 \cdot 2}

2^{2} - 4 \cdot 2 (- 144) = 34

x_{1, 2} = \frac{- 2 \pm 34}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 2 + 34}{2 \cdot 2}, x_{2} = \frac{- 2 - 34}{2 \cdot 2}

x = \frac{- 2 + 34}{2 \cdot 2} : 8

x = \frac{- 2 - 34}{2 \cdot 2} : - 9

The solutions to the quadratic equation are:

x = 8, x = - 9

12 x^{2} - 72 x + 96 = 0

- 3 ∣ x - 6 ∣ \geq - 15

2 x^{2} + 4 x - 9 = 2 (x - 1)

\frac{x - 10}{8} = 10
