8 x^{2} + 64 x - 168 = 0

x = - 4 + 37, x = - 4 - 37

Decimal Notation

x = 2.08276 \dots, x = - 10.08276 \dots

Solution steps

8 x^{2} + 64 x - 168 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 64 \pm 6 4 ^{2} - 4 \cdot 8 ( - 168 )}{2 \cdot 8}

6 4^{2} - 4 \cdot 8 (- 168) = 1637

x_{1, 2} = \frac{- 64 \pm 16 37}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- 64 + 16 37}{2 \cdot 8}, x_{2} = \frac{- 64 - 16 37}{2 \cdot 8}

x = \frac{- 64 + 16 37}{2 \cdot 8} : - 4 + 37

x = \frac{- 64 - 16 37}{2 \cdot 8} : - 4 - 37

The solutions to the quadratic equation are:

x = - 4 + 37, x = - 4 - 37

x^{2} + 14 x + 45 = 0

x^{2} + 32 = 21

2 + 4 + 6 + 2 n = n (n + 1)

x^{2} + 3 = 12

x^{2} + 7 x
