u^{2} = 9

u = 3, u = - 3

Solution steps

u^{2} = 9

For

x^{2} = f (a)

the solutions are

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

u = 9, u = - 9

9 = 3

- 9 = - 3

u = 3, u = - 3

- 16 t^{2} + 40 = 40 (t)

(x + 5)^{2} - 18 = 63

x, 52 x^{2} + 72 x y + 73 y^{2} - 40 x + 30 y = 75

2 z^{2} - 3 z + 3 = 0

r^{2} + 3 r + r = 0
