(7 x)^{2} - 49 = 0

x = 1, x = - 1

Solution steps

(7 x)^{2} - 49 = 0

Expand

(7 x)^{2} - 49 : 49 x^{2} - 49

49 x^{2} - 49 = 0

Move

49

to the right side

49 x^{2} = 49

Divide both sides by

49

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

- 0.1 (49 x^{2} - 920 x - 12) = 0

2 = 0.013 x^{2} - 1.18 x + 28.24

(x - 6.25)^{2} = 3

4 y^{2} - 215 y + 2875 = 0

x, a = x^{2} m + x^{2} n + x^{2} q
