7 x^{2} - 13 + 6 = 0

x = 1, x = - 1

Solution steps

7 x^{2} - 13 + 6 = 0

Move

13

to the right side

7 x^{2} + 6 = 13

Move

6

to the right side

7 x^{2} = 7

Divide both sides by

7

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

2 x^{2} - 4 x + 5

x^{2} + 4 x = x + 10

x^{2} + 5 x + 9 = 0

x^{2} + 6 x + 13

x^{2} + 17 = 0
