86 = 6 + 8 (x^{2})

x = 10, x = - 10

Decimal Notation

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

Solution steps

86 = 6 + 8 (x^{2})

Refine

86 = 6 + 8 x^{2}

Switch sides

6 + 8 x^{2} = 86

Move

6

to the right side

8 x^{2} = 80

Divide both sides by

8

x^{2} = 10

For

x^{2} = f (a)

the solutions are

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

x = 10, x = - 10

x^{2} + 8 x + 4

x^{2} + 8 x + 2

4 x^{2} + 96 = - 40 x

3 x^{2} - 6 x - 1 = 0

0 = - x^{2} + 2 x + 8
