7 x^{2} - x^{2} = 168

x = 27, x = - 27

Solution steps

7 x^{2} - x^{2} = 168

Add similar elements:

7 x^{2} - x^{2} = 6 x^{2}

6 x^{2} = 168

Divide both sides by

6

x^{2} = 28

For

x^{2} = f (a)

the solutions are

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

x = 28, x = - 28

28 = 27

- 28 = - 27

x = 27, x = - 27

x^{2} + 10 x = 2

z^{2} + z - 6 = 0

(2 n - 1) v^{2} - 2 n v + 1 = 0

2 x (x - 8) = 0

2 y^{2} = - 40
