5 - 7 x^{2} = - 86

x = 13, x = - 13

Decimal Notation

x = 3.60555 \dots, x = - 3.60555 \dots

Solution steps

5 - 7 x^{2} = - 86

Move

5

to the right side

- 7 x^{2} = - 91

Divide both sides by

- 7

x^{2} = 13

For

x^{2} = f (a)

the solutions are

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

x = 13, x = - 13

4 x^{2} - 8 x + 11 = 0

x^{2} - 8 x - 36 = 0

x, x^{2} + x y + y^{2} = C

(y - \frac{1}{2})^{2} = \frac{1}{4}

x^{2} = - 8 x - 12
