7 x^{2} - 3 = 109

x = 4, x = - 4

Solution steps

7 x^{2} - 3 = 109

Move

3

to the right side

7 x^{2} = 112

Divide both sides by

7

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

5 x^{2} - 8 x = 6

- x^{2} + 15 x + 100 = 0

24 x^{2} + 2 x - 15 = 0

(2 y + 3)^{2} = 9

w^{2} + 7 w - 18 = 0
