2 x^{2} - 3 = 125

x = 8, x = - 8

Solution steps

2 x^{2} - 3 = 125

Move

3

to the right side

2 x^{2} = 128

Divide both sides by

2

x^{2} = 64

For

x^{2} = f (a)

the solutions are

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

x = 64, x = - 64

64 = 8

- 64 = - 8

x = 8, x = - 8

x^{2} - 2451 x - 2631 = 0

4 x^{2} - 9 x - 90 = 0

- 0.1 x^{2} + 80 = 0.3 x^{2} + x + 30

8 x^{2} + 16 x = 42

x, x^{2} = 2 y^{2} lo g_{10} (y)
