8 r^{2} - 17 = 2471

r = 311, r = - 311

Decimal Notation

r = 17.63519 \dots, r = - 17.63519 \dots

Solution steps

8 r^{2} - 17 = 2471

Move

17

to the right side

8 r^{2} = 2488

Divide both sides by

8

r^{2} = 311

For

x^{2} = f (a)

the solutions are

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

r = 311, r = - 311

\frac{4}{9} \cdot 4

2 x^{2} + 2 y^{2} - 4 x + 4 y + 2

- \frac{2}{5} (x + 10) = \frac{3}{5} x

2 v^{2} + 3 v - 9

\frac{1}{5} + \frac{1}{7}
