80 - 5 x^{2} = 0

x = 4, x = - 4

Solution steps

80 - 5 x^{2} = 0

Move

80

to the right side

- 5 x^{2} = - 80

Divide both sides by

- 5

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

z^{2} + 8 z + 15 = 0

11 y^{2} - 12 y + 4 = 6 y^{2}

x^{2} - 2 x - 2 = 0, x > 0

y, x^{2} y^{9} = 2

x^{2} - 10 x - 9
