x^{2} - 441 = 0

x = 21, x = - 21

Solution steps

x^{2} - 441 = 0

Move

441

to the right side

x^{2} = 441

For

x^{2} = f (a)

the solutions are

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

x = 441, x = - 441

441 = 21

- 441 = - 21

x = 21, x = - 21

2 + x^{2} = 0

1 - 0.4 z + 0.4 z^{2} = 0

2 x^{2} = 30 - 7 x

7 x (x - 2) = 0

10 x^{2} + 5 (- 5 x)^{2} + 4 x (- 5 x) = 110
