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

x = 8, x = - 9

Solution steps

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

Move

2 x

to the left side

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

Write in the standard form

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

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

x^{2} + 1.4 x + 1 = 0

10000 x^{2} - 64 = 0

x, x^{2} - 8 x + 41 = 0

x, \frac{8 x - 2 y}{2 y + 3} = 2 x^{2} - 1

6 x^{2} = 5 x + 4
