25 x^{2} - 225 = 0

x = 3, x = - 3

Solution steps

25 x^{2} - 225 = 0

Move

225

to the right side

25 x^{2} = 225

Divide both sides by

25

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

6 x^{2} + 48 x = 0

(x + 2)^{2} + (x - 3)^{2} = (2 x - 1)^{2}

x^{2} - 31 - 2 x = - 6 - 3 x^{2} - 2 x

x^{2} + (m + 2) x + 2 m = 0

7^{2} + 5^{2} = x^{2}
