5 - 2 x^{2} = - 15

x = 10, x = - 10

Decimal Notation

x = 3.16227 \dots, x = - 3.16227 \dots

Solution steps

5 - 2 x^{2} = - 15

Move

5

to the right side

- 2 x^{2} = - 20

Divide both sides by

- 2

x^{2} = 10

For

x^{2} = f (a)

the solutions are

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

x = 10, x = - 10

\frac{25 x ^{2} - 81}{x ^{2} - 36} \leq 0

3 \cdot 8

3 z^{2} + 12 z - 20 = 5 z

\frac{2 ^{- 3}}{2 ^{- 5}}

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