x (x + 1) = 6

x = 2, x = - 3

Solution steps

x (x + 1) = 6

Expand

x (x + 1) : x^{2} + x

x^{2} + x = 6

Move

6

to the left side

x^{2} + x - 6 = 0

Solve with the quadratic formula

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

1^{2} - 4 \cdot 1 \cdot (- 6) = 5

x_{1, 2} = \frac{- 1 \pm 5}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 1 + 5}{2 \cdot 1}, x_{2} = \frac{- 1 - 5}{2 \cdot 1}

x = \frac{- 1 + 5}{2 \cdot 1} : 2

x = \frac{- 1 - 5}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

x = 2, x = - 3

\frac{4}{m} \cdot \frac{m + 3}{12}

∣ 2 y + 11 ∣ = 2

∣ - 4 x + 7 ∣ = 0

∣ 5 x + 2 ∣ > 0

3 x^{2} - 12 x + 9 = 0
