352 = 7 x^{2} + 9

x = 7, x = - 7

Solution steps

352 = 7 x^{2} + 9

Switch sides

7 x^{2} + 9 = 352

Move

9

to the right side

7 x^{2} = 343

Divide both sides by

7

x^{2} = 49

For

x^{2} = f (a)

the solutions are

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

x = 49, x = - 49

49 = 7

- 49 = - 7

x = 7, x = - 7

11 x^{2} - 13 x = x (8 - 3 x)

(2 (x^{2}) - 40) 2 = 20

- 4 x^{2} - 8 x + 15 = 0

y, y^{2} = x + C x^{3}

(x - 8)^{2} = - 36
