x^{2} - 9 x - 12 = - 4 x - 6

x = 6, x = - 1

Solution steps

x^{2} - 9 x - 12 = - 4 x - 6

Move

6

to the left side

x^{2} - 9 x - 6 = - 4 x

Move

4 x

to the left side

x^{2} - 5 x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 1 \cdot ( - 6 )}{2 \cdot 1}

(- 5)^{2} - 4 \cdot 1 \cdot (- 6) = 7

x_{1, 2} = \frac{- ( - 5 ) \pm 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 7}{2 \cdot 1}, x_{2} = \frac{- ( - 5 ) - 7}{2 \cdot 1}

x = \frac{- ( - 5 ) + 7}{2 \cdot 1} : 6

x = \frac{- ( - 5 ) - 7}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

x = 6, x = - 1

6 x^{4} - 9 x^{3} - 36 x^{2} + 54 x

∣ 1 - 5 x ∣ + 5 = 6

x + 2 = 4

16 j^{2} + 24 j + 9

\frac{1}{2} x - \frac{4}{3} > 2
