z^{2} - 13 z - 30 = 0

z = 15, z = - 2

Solution steps

z^{2} - 13 z - 30 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 13)^{2} - 4 \cdot 1 \cdot (- 30) = 17

z_{1, 2} = \frac{- ( - 13 ) \pm 17}{2 \cdot 1}

Separate the solutions

z_{1} = \frac{- ( - 13 ) + 17}{2 \cdot 1}, z_{2} = \frac{- ( - 13 ) - 17}{2 \cdot 1}

z = \frac{- ( - 13 ) + 17}{2 \cdot 1} : 15

z = \frac{- ( - 13 ) - 17}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

z = 15, z = - 2
