z^2+7z+10=0

Solution

z^{2} + 7 z + 10 = 0

Solution

z = - 2, z = - 5

Solution steps

z^{2} + 7 z + 10 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 1 \cdot 10}{2 \cdot 1}

7^{2} - 4 \cdot 1 \cdot 10 = 3

z_{1, 2} = \frac{- 7 \pm 3}{2 \cdot 1}

Separate the solutions

z_{1} = \frac{- 7 + 3}{2 \cdot 1}, z_{2} = \frac{- 7 - 3}{2 \cdot 1}

z = \frac{- 7 + 3}{2 \cdot 1} : - 2

z = \frac{- 7 - 3}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

z = - 2, z = - 5
