roots

2 x^{2} - 1

x = \frac{1}{2}, x = - \frac{1}{2}

Solution steps

2 x^{2} - 1

The roots are the intercepts with the x-axis

(y = 0)

2 x^{2} - 1 = 0

Move

1

to the right side

2 x^{2} = 1

Divide both sides by

2

x^{2} = \frac{1}{2}

For

x^{2} = f (a)

the solutions are

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

x = \frac{1}{2}, x = - \frac{1}{2}

\frac{1}{2} = \frac{1}{2}

- \frac{1}{2} = - \frac{1}{2}

x = \frac{1}{2}, x = - \frac{1}{2}

4 x^{2} - 16 x + 16 = 16 x - 32

24 x^{2} - 4 x - 4 = 12

5 (x + 8)^{2} = 60

5 x^{2} + 30 = 0

19 x^{2} - 120 x + 125 = 0
