x^{2} + 14 x = 8

x = - 7 + 57, x = - 7 - 57

Decimal Notation

x = 0.54983 \dots, x = - 14.54983 \dots

Solution steps

x^{2} + 14 x = 8

Move

8

to the left side

x^{2} + 14 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 \cdot 1 \cdot ( - 8 )}{2 \cdot 1}

1 4^{2} - 4 \cdot 1 \cdot (- 8) = 257

x_{1, 2} = \frac{- 14 \pm 2 57}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 14 + 2 57}{2 \cdot 1}, x_{2} = \frac{- 14 - 2 57}{2 \cdot 1}

x = \frac{- 14 + 2 57}{2 \cdot 1} : - 7 + 57

x = \frac{- 14 - 2 57}{2 \cdot 1} : - 7 - 57

The solutions to the quadratic equation are:

x = - 7 + 57, x = - 7 - 57

x (x + 3) + 2 = 3 x

3 x^{2} + 12 x + 4 = 0

2 x^{2} + 4 = - 8 x

x, x^{2} + 6 x + 10 = 0

A = x (25 - x)
