8 z^{2} - 200 = 0

z = 5, z = - 5

Solution steps

8 z^{2} - 200 = 0

Move

200

to the right side

8 z^{2} = 200

Divide both sides by

8

z^{2} = 25

For

x^{2} = f (a)

the solutions are

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

z = 25, z = - 25

25 = 5

- 25 = - 5

z = 5, z = - 5

x, x^{2} + 2 x - 5 = 0

0 = - 4.9 t^{2} + 900 t

x, k x^{2} - 4 x + \frac{1}{2} = 0

(2 x + 6) (2 x - 6) = (2 x + 9) (3 x - 4)

- 3 (x - 8) (5 x - 1) = 0
