x^{2} + 12 x = - 28

x = 2 (2 - 3), x = - 2 (3 + 2)

Decimal Notation

x = - 3.17157 \dots, x = - 8.82842 \dots

Solution steps

x^{2} + 12 x = - 28

Move

28

to the left side

x^{2} + 12 x + 28 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 \cdot 1 \cdot 28}{2 \cdot 1}

1 2^{2} - 4 \cdot 1 \cdot 28 = 42

x_{1, 2} = \frac{- 12 \pm 4 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 12 + 4 2}{2 \cdot 1}, x_{2} = \frac{- 12 - 4 2}{2 \cdot 1}

x = \frac{- 12 + 4 2}{2 \cdot 1} : 2 (2 - 3)

x = \frac{- 12 - 4 2}{2 \cdot 1} : - 2 (3 + 2)

The solutions to the quadratic equation are:

x = 2 (2 - 3), x = - 2 (3 + 2)

7 - 3 x > 0
