x (x + 7) = 1 + 7 x

x = 1, x = - 1

Solution steps

x (x + 7) = 1 + 7 x

Expand

x (x + 7) : x^{2} + 7 x

x^{2} + 7 x = 1 + 7 x

Move

7 x

to the left side

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

x^{2} + 16 = - 12 x

4 x^{2} - 6 x - 18 = 0

a^{2} + 8 a = 0

4 y^{2} = - y + 3

10 x^{2} - 31 x + 15 = 0
