x^{2} - 8 x - 84 = 0

x = 14, x = - 6

Solution steps

x^{2} - 8 x - 84 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 1 \cdot ( - 84 )}{2 \cdot 1}

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

x = 14, x = - 6

- 5 < 5 y - 7 < 13

(a + b)^{2} - 2 (a + b) + 1

72 \cdot 3

- 16 t^{2} + 16 t + 96

5 x^{2} = 3 x
