r^{2} = 18

r = 32, r = - 32

Decimal Notation

r = 4.24264 \dots, r = - 4.24264 \dots

Solution steps

r^{2} = 18

For

x^{2} = f (a)

the solutions are

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

r = 18, r = - 18

18 = 32

- 18 = - 32

r = 32, r = - 32

- 2 x^{2} = 36 - 18 x

2 x^{2} - 12 x = - 3

x^{2} + 7 x + 21 = 0

5 x^{2} - 1 = 7 x

- 7 - 4 (x + 3)^{2} = - 71
