x^{2} + \frac{6}{7} x - 55 = 0

x = 7, x = - \frac{55}{7}

Decimal Notation

x = 7, x = - 7.85714 \dots

Solution steps

x^{2} + \frac{6}{7} x - 55 = 0

Multiply both sides by

7

7 x^{2} + 6 x - 385 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 7 ( - 385 )}{2 \cdot 7}

6^{2} - 4 \cdot 7 (- 385) = 104

x_{1, 2} = \frac{- 6 \pm 104}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- 6 + 104}{2 \cdot 7}, x_{2} = \frac{- 6 - 104}{2 \cdot 7}

x = \frac{- 6 + 104}{2 \cdot 7} : 7

x = \frac{- 6 - 104}{2 \cdot 7} : - \frac{55}{7}

The solutions to the quadratic equation are:

x = 7, x = - \frac{55}{7}

6 - 4

5 n^{2} + 8 n + 3

0 < x

x \cdot \frac{1}{2} x^{- \frac{1}{2}}

y - \frac{13}{23} = - \frac{11}{23}
