4 x^{2} - 1 = 64

x = \frac{65}{2}, x = - \frac{65}{2}

Decimal Notation

x = 4.03112 \dots, x = - 4.03112 \dots

Solution steps

4 x^{2} - 1 = 64

Move

1

to the right side

4 x^{2} = 65

Divide both sides by

4

x^{2} = \frac{65}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{65}{4}, x = - \frac{65}{4}

\frac{65}{4} = \frac{65}{2}

- \frac{65}{4} = - \frac{65}{2}

x = \frac{65}{2}, x = - \frac{65}{2}
