z^{2} = 90

z = 310, z = - 310

Decimal Notation

z = 9.48683 \dots, z = - 9.48683 \dots

Solution steps

z^{2} = 90

For

x^{2} = f (a)

the solutions are

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

z = 90, z = - 90

90 = 310

- 90 = - 310

z = 310, z = - 310

z^{2} = 9 z

x^{2} - 40 x + 359 = 0

z^{2} = - 7

x (x + 2) = - 17

2 x^{2} - 108 = 0
