81 - x^{2} = - 9

x = 310, x = - 310

Decimal Notation

x = 9.48683 \dots, x = - 9.48683 \dots

Solution steps

81 - x^{2} = - 9

Move

81

to the right side

- x^{2} = - 90

Divide both sides by

- 1

x^{2} = 90

For

x^{2} = f (a)

the solutions are

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

x = 90, x = - 90

90 = 310

- 90 = - 310

x = 310, x = - 310

(x + 3)^{2} + (x + 2) (x - 2) = x (x - 1) - 5

u^{2} - 25 u + 144 = 0

x^{2} = 4 x + 32

x^{2} - 1 = 0

x, f = x^{2} - h^{2}
