s^2-s-12=0

Solution

s^{2} - s - 12 = 0

Solution

s = 4, s = - 3

Solution steps

s^{2} - s - 12 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot ( - 12 )}{2 \cdot 1}

(- 1)^{2} - 4 \cdot 1 \cdot (- 12) = 7

s_{1, 2} = \frac{- ( - 1 ) \pm 7}{2 \cdot 1}

Separate the solutions

s_{1} = \frac{- ( - 1 ) + 7}{2 \cdot 1}, s_{2} = \frac{- ( - 1 ) - 7}{2 \cdot 1}

s = \frac{- ( - 1 ) + 7}{2 \cdot 1} : 4

s = \frac{- ( - 1 ) - 7}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

s = 4, s = - 3
