x (x + 2) = 2 x + 9

x = 3, x = - 3

Solution steps

x (x + 2) = 2 x + 9

Expand

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

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

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

6.3 \cdot 1 0^{- 5} = \frac{x ^{2}}{0.008}

8 x^{2} - 96 x = 0

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

8 - P^{2} = - 2 + P^{2}
