x^{2} + 2 x - 9 = 2 x

x = 3, x = - 3

Solution steps

x^{2} + 2 x - 9 = 2 x

Move

9

to the right side

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

Move

2 x

to the left 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

9 x^{2} - 16 = 0

x^{2} - 4 x + 4

a, a^{2} = b^{2}

2 x^{2} + 12 x = 18

4 (x + 7)^{2} + 22 = 38
