400 - x^{2} = 0

x = 20, x = - 20

Solution steps

400 - x^{2} = 0

Move

400

to the right side

- x^{2} = - 400

Divide both sides by

- 1

x^{2} = 400

For

x^{2} = f (a)

the solutions are

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

x = 400, x = - 400

400 = 20

- 400 = - 20

x = 20, x = - 20

x, 0 = a x^{2} + b x + c

9 x^{2} - 6 = 0

x^{2} + 14 x + 3

- 3 x^{2} + 6 x - 15 = 0

5 a^{2} - 26 a = 24
