300 = 500 - 2 x^{2}

x = 10, x = - 10

Solution steps

300 = 500 - 2 x^{2}

Switch sides

500 - 2 x^{2} = 300

Move

500

to the right side

- 2 x^{2} = - 200

Divide both sides by

- 2

x^{2} = 100

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 100, x = - 100

100 = 10

- 100 = - 10

x = 10, x = - 10

2 (x^{2} + 7) = x^{2} + 10

x, \frac{y + 3}{2} x^{2} - (y + 2) x + \frac{y + 1}{2} = 0

1 - \frac{1}{6} x - \frac{1}{3} x^{2} = 0

- 3 x^{2} + 14 x - 12 = 0

2 x^{2} + 2 x - 14 = 10
