8 x^{2} - 19 = 15

x = \frac{17}{2}, x = - \frac{17}{2}

Decimal Notation

x = 2.06155 \dots, x = - 2.06155 \dots

Solution steps

8 x^{2} - 19 = 15

Move

19

to the right side

8 x^{2} = 34

Divide both sides by

8

x^{2} = \frac{17}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{17}{4}, x = - \frac{17}{4}

\frac{17}{4} = \frac{17}{2}

- \frac{17}{4} = - \frac{17}{2}

x = \frac{17}{2}, x = - \frac{17}{2}

3 x^{2} - 2.2 + 5 x = 0

1000000 = 25 t^{2} + 72 t + 100

- 2 x^{2} + 24 = 8 x

7 x^{2} - 1 = - 2 x

x, x^{2} - 25 = 0
