(x - 2)^{2} = 2 x + 4

x = 6, x = 0

Solution steps

(x - 2)^{2} = 2 x + 4

Expand

(x - 2)^{2} : x^{2} - 4 x + 4

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

Move

4

to the left side

x^{2} - 4 x = 2 x

Move

2 x

to the left side

x^{2} - 6 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot 0 = 6

x_{1, 2} = \frac{- ( - 6 ) \pm 6}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 6}{2 \cdot 1}, x_{2} = \frac{- ( - 6 ) - 6}{2 \cdot 1}

x = \frac{- ( - 6 ) + 6}{2 \cdot 1} : 6

x = \frac{- ( - 6 ) - 6}{2 \cdot 1} : 0

The solutions to the quadratic equation are:

x = 6, x = 0

4 y^{2} - 5 y = 9

- 4.9 r^{2} - 120 r + 90 = 0

3 x^{2} - 8 x + 15 = 0

3 (x - 2)^{2} - 8 = 5

10 y^{2} - 12 y - 16 = 0
