x^{2} + 8 x = 11

x = - 4 + 33, x = - 4 - 33

Decimal Notation

x = 1.19615 \dots, x = - 9.19615 \dots

Solution steps

x^{2} + 8 x = 11

Move

11

to the left side

x^{2} + 8 x - 11 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot ( - 11 )}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot (- 11) = 63

x_{1, 2} = \frac{- 8 \pm 6 3}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 8 + 6 3}{2 \cdot 1}, x_{2} = \frac{- 8 - 6 3}{2 \cdot 1}

x = \frac{- 8 + 6 3}{2 \cdot 1} : - 4 + 33

x = \frac{- 8 - 6 3}{2 \cdot 1} : - 4 - 33

The solutions to the quadratic equation are:

x = - 4 + 33, x = - 4 - 33

16 (4 - 4 x)^{2} - 11 = - 7

x, x^{2} - 2 x y + y^{2} = 0

2 x^{2} + 12 = 36

5 x^{2} + 7 x + 6 = 0

x^{2} + 17 x + 50 = 0
