x^{2} - 4 x - 224 = 0

x = 2 (1 + 57), x = 2 (1 - 57)

Solution steps

x^{2} - 4 x - 224 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 \cdot 1 \cdot ( - 224 )}{2 \cdot 1}

(- 4)^{2} - 4 \cdot 1 \cdot (- 224) = 457

x_{1, 2} = \frac{- ( - 4 ) \pm 4 57}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 4 57}{2 \cdot 1}, x_{2} = \frac{- ( - 4 ) - 4 57}{2 \cdot 1}

x = \frac{- ( - 4 ) + 4 57}{2 \cdot 1} : 2 (1 + 57)

x = \frac{- ( - 4 ) - 4 57}{2 \cdot 1} : 2 (1 - 57)

The solutions to the quadratic equation are:

x = 2 (1 + 57), x = 2 (1 - 57)

- \frac{1}{2} x - 7 = 18
