- \frac{1}{2} x^{2} + 1 = - 39

x = 45, x = - 45

Decimal Notation

x = 8.94427 \dots, x = - 8.94427 \dots

Solution steps

- \frac{1}{2} x^{2} + 1 = - 39

Move

1

to the right side

- \frac{1}{2} x^{2} = - 40

Multiply both sides by

- 2

x^{2} = 80

For

x^{2} = f (a)

the solutions are

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

x = 80, x = - 80

80 = 45

- 80 = - 45

x = 45, x = - 45

10 \geq 7 + x - 2 x

1 0^{- 5}

\frac{x - 2}{5} + 3 = 12

v^{2} = - 2

8 m^{2} - 4 = 0
