6 r^{2} - r - 1 = 0

r = \frac{1}{2}, r = - \frac{1}{3}

Decimal Notation

r = 0.5, r = - 0.33333 \dots

Solution steps

6 r^{2} - r - 1 = 0

Solve with the quadratic formula

r_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 6 ( - 1 )}{2 \cdot 6}

(- 1)^{2} - 4 \cdot 6 (- 1) = 5

r_{1, 2} = \frac{- ( - 1 ) \pm 5}{2 \cdot 6}

Separate the solutions

r_{1} = \frac{- ( - 1 ) + 5}{2 \cdot 6}, r_{2} = \frac{- ( - 1 ) - 5}{2 \cdot 6}

r = \frac{- ( - 1 ) + 5}{2 \cdot 6} : \frac{1}{2}

r = \frac{- ( - 1 ) - 5}{2 \cdot 6} : - \frac{1}{3}

The solutions to the quadratic equation are:

r = \frac{1}{2}, r = - \frac{1}{3}
