x^{2} + 16 = 81

x = 65, x = - 65

Decimal Notation

x = 8.06225 \dots, x = - 8.06225 \dots

Solution steps

x^{2} + 16 = 81

Move

16

to the right side

x^{2} = 65

For

x^{2} = f (a)

the solutions are

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

x = 65, x = - 65

- 3 x^{2} + 2 x - 5 = 0

5 X^{2} - 500 = 0

3 x^{2} + 32 x = 11

\frac{1}{2} x^{2} + x + 4 = 0

4 x^{2} = 8 x - 1
