- \frac{1}{2} x^{2} + 40 = 0

x = 45, x = - 45

Decimal Notation

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

Solution steps

- \frac{1}{2} x^{2} + 40 = 0

Move

40

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

x^{3} - 7 x^{2} - 8 x

6 (x - 5) = 54

- 4 (5 x - 7) < - 24 x + 8

\frac{8 ^{7}}{8 ^{5}}

x^{2} + 3 x
