5 n^{2} = 245

n = 7, n = - 7

Solution steps

5 n^{2} = 245

Divide both sides by

5

n^{2} = 49

For

x^{2} = f (a)

the solutions are

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

n = 49, n = - 49

49 = 7

- 49 = - 7

n = 7, n = - 7

4 x^{2} - 10 = 0

(5 + 47) x^{2} + (4 - 27) x - 1 = 0

x^{2} + 4 x + 3 = 0

- x^{2} - 10 x - 16 = 0

x^{2} - 7 x = 12.75
