5 (x^{2} - 7) - 1 = 9

x = 3, x = - 3

Solution steps

5 (x^{2} - 7) - 1 = 9

Move

1

to the right side

5 (x^{2} - 7) = 10

Divide both sides by

5

x^{2} - 7 = 2

Move

7

to the right side

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

25 x^{2} + 375 x + 1250 = 0

x^{2} - 2 x + 10

6 x^{2} - 3 x + 6 = 0

x^{2} - 18 x = - 6

9 x^{2} + 25 = 106
