x^{2} - 16 x + 7 = 0

x = 8 + 57, x = 8 - 57

Decimal Notation

x = 15.54983 \dots, x = 0.45016 \dots

Solution steps

x^{2} - 16 x + 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 1 \cdot 7}{2 \cdot 1}

(- 16)^{2} - 4 \cdot 1 \cdot 7 = 257

x_{1, 2} = \frac{- ( - 16 ) \pm 2 57}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 2 57}{2 \cdot 1}, x_{2} = \frac{- ( - 16 ) - 2 57}{2 \cdot 1}

x = \frac{- ( - 16 ) + 2 57}{2 \cdot 1} : 8 + 57

x = \frac{- ( - 16 ) - 2 57}{2 \cdot 1} : 8 - 57

The solutions to the quadratic equation are:

x = 8 + 57, x = 8 - 57

7 x^{2} - 35 x - 28

\frac{1}{3} (5)

3 x + 2 x + 6 = 6 x - 5

x - 4 \leq 2

- 5 x^{2} - 10 x
