81 - x^{2} = 2 x^{2}

x = 33, x = - 33

Solution steps

81 - x^{2} = 2 x^{2}

Move

81

to the right side

- x^{2} = 2 x^{2} - 81

Move

2 x^{2}

to the left side

- 3 x^{2} = - 81

Divide both sides by

- 3

x^{2} = 27

For

x^{2} = f (a)

the solutions are

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

x = 27, x = - 27

27 = 33

- 27 = - 33

x = 33, x = - 33

2 (x + 5)^{2} - 6 = 0

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

x^{2} - 9 x = x + 24

2 x^{2} + 5 x = 0

8 x^{2} - 16 x - 4 = 0
