5 x^{2} = 405

x = 9, x = - 9

Solution steps

5 x^{2} = 405

Divide both sides by

5

x^{2} = 81

For

x^{2} = f (a)

the solutions are

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

x = 81, x = - 81

81 = 9

- 81 = - 9

x = 9, x = - 9

s^{2} + 6 s + 144 = 0

2 x = x^{2} + 2

z, x^{2} + y^{2} + (z - 5)^{2} = 25

2 x^{2} + 10 x = 48

x (x + 1) = 56
