x^{2} + 1 = 8

x = 7, x = - 7

Decimal Notation

x = 2.64575 \dots, x = - 2.64575 \dots

Solution steps

x^{2} + 1 = 8

Move

1

to the right side

x^{2} = 7

For

x^{2} = f (a)

the solutions are

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

x = 7, x = - 7

x^{2} = 8 - 5 x

0.4048 x^{2} - 60.726 x + 1812.9 = 0

x^{2} - 15 x - 76 = 0

2 p^{2} + 3 = 21

2 x^{2} = - 16
