x^{2} - 10 x - 7 = 0

x = 5 + 42, x = 5 - 42

Decimal Notation

x = 10.65685 \dots, x = - 0.65685 \dots

Solution steps

x^{2} - 10 x - 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot ( - 7 )}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot (- 7) = 82

x_{1, 2} = \frac{- ( - 10 ) \pm 8 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 10 ) + 8 2}{2 \cdot 1}, x_{2} = \frac{- ( - 10 ) - 8 2}{2 \cdot 1}

x = \frac{- ( - 10 ) + 8 2}{2 \cdot 1} : 5 + 42

x = \frac{- ( - 10 ) - 8 2}{2 \cdot 1} : 5 - 42

The solutions to the quadratic equation are:

x = 5 + 42, x = 5 - 42

64 x^{2} = 49

36 - 85 x + 9 x^{2} = 0

m + 4 = \frac{13}{2}

2 x^{2} - 9 x - 26 = 0

\frac{( 25 + 4 )}{3} + 25 = 20
