7 n^{2} - 7 = 105

n = 4, n = - 4

Solution steps

7 n^{2} - 7 = 105

Move

7

to the right side

7 n^{2} = 112

Divide both sides by

7

n^{2} = 16

For

x^{2} = f (a)

the solutions are

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

n = 16, n = - 16

16 = 4

- 16 = - 4

n = 4, n = - 4

2 x^{2} - 4 x + 13

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

5 t^{2} + 3 t - 2 = 0

25 x^{2} + 30 x + 12

t, h = v t - g t^{2}
