80 = x^{2} + 1

x = 79, x = - 79

Decimal Notation

x = 8.88819 \dots, x = - 8.88819 \dots

Solution steps

80 = x^{2} + 1

Switch sides

x^{2} + 1 = 80

Move

1

to the right side

x^{2} = 79

For

x^{2} = f (a)

the solutions are

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

x = 79, x = - 79

2 x^{2} + 11 x - 11 = 6 x - 8

- x^{2} + 5 x + 25 = 0

4 x^{2} - 12 x + 1 = 0

3 x^{2} + 33 x + 30 = 0

a^{2} - 3 a + 2 = 0
