x^2-20x+84=0

Solution

x^{2} - 20 x + 84 = 0

Solution

x = 14, x = 6

Solution steps

x^{2} - 20 x + 84 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 1 \cdot 84}{2 \cdot 1}

(- 20)^{2} - 4 \cdot 1 \cdot 84 = 8

x_{1, 2} = \frac{- ( - 20 ) \pm 8}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 8}{2 \cdot 1}, x_{2} = \frac{- ( - 20 ) - 8}{2 \cdot 1}

x = \frac{- ( - 20 ) + 8}{2 \cdot 1} : 14

x = \frac{- ( - 20 ) - 8}{2 \cdot 1} : 6

The solutions to the quadratic equation are:

x = 14, x = 6
