- 31 = 2 - 3 a^{2}

a = 11, a = - 11

Decimal Notation

a = 3.31662 \dots, a = - 3.31662 \dots

Solution steps

- 31 = 2 - 3 a^{2}

Switch sides

2 - 3 a^{2} = - 31

Move

2

to the right side

- 3 a^{2} = - 33

Divide both sides by

- 3

a^{2} = 11

For

x^{2} = f (a)

the solutions are

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

a = 11, a = - 11

x, 3 x^{2} - 2 x + 2 = 0

x, f^{- 1} (x) = x^{2} + 5

(x - 1) (2 x - 3) = 1

84 = \frac{1}{2} x (3 x + 3)

9 v^{2} + 2 = - 4 v
