x^{2} - 18 = - x^{2}

x = 3, x = - 3

Solution steps

x^{2} - 18 = - x^{2}

Move

18

to the right side

x^{2} = - x^{2} + 18

Move

x^{2}

to the left side

2 x^{2} = 18

Divide both sides by

2

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

i^{- 4}

5 x^{2} = 30 x - 10 x^{2}

a + \frac{3}{4} a = 21

1 + 2 ∣ x - 1 ∣ \leq 9

10 < 2 x - 1 \leq x + 5
