11 s^{2} - 26 s - 61 = 0

s = \frac{13 + 2 210}{11}, s = \frac{13 - 2 210}{11}

Solution steps

11 s^{2} - 26 s - 61 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- ( - 26 ) \pm ( - 26 ) ^{2} - 4 \cdot 11 ( - 61 )}{2 \cdot 11}

(- 26)^{2} - 4 \cdot 11 (- 61) = 4210

s_{1, 2} = \frac{- ( - 26 ) \pm 4 210}{2 \cdot 11}

Separate the solutions

s_{1} = \frac{- ( - 26 ) + 4 210}{2 \cdot 11}, s_{2} = \frac{- ( - 26 ) - 4 210}{2 \cdot 11}

s = \frac{- ( - 26 ) + 4 210}{2 \cdot 11} : \frac{13 + 2 210}{11}

s = \frac{- ( - 26 ) - 4 210}{2 \cdot 11} : \frac{13 - 2 210}{11}

The solutions to the quadratic equation are:

s = \frac{13 + 2 210}{11}, s = \frac{13 - 2 210}{11}
