x (x + 6) - (x - 4) = x

x = - 2

Solution steps

x (x + 6) - (x - 4) = x

Expand

x (x + 6) - (x - 4) : x^{2} + 5 x + 4

x^{2} + 5 x + 4 = x

Move

x

to the left side

x^{2} + 4 x + 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 1 \cdot 4}{2 \cdot 1}

4^{2} - 4 \cdot 1 \cdot 4 = 0

x_{1, 2} = \frac{- 4 \pm 0}{2 \cdot 1}

x = \frac{- 4}{2 \cdot 1}

\frac{- 4}{2 \cdot 1} = - 2

x = - 2

The solution to the quadratic equation is:

x = - 2

(2^{2} 2^{- 3} 3^{- 2} 3^{3} 4^{- 2} 4^{3})^{2}

15 y^{2} - 30 = 22 y + 7

3 x + 23 = 2 x + 59

x = x + \frac{x}{3} + 1

3 (x - 4) = 8 - 5 (3 x + 1)
