x(x+10)+20=-5

Solution

x (x + 10) + 20 = - 5

Solution

x = - 5

Solution steps

x (x + 10) + 20 = - 5

Expand

x (x + 10) + 20 : x^{2} + 10 x + 20

x^{2} + 10 x + 20 = - 5

Move

5

to the left side

x^{2} + 10 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot 25}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot 25 = 0

x_{1, 2} = \frac{- 10 \pm 0}{2 \cdot 1}

x = \frac{- 10}{2 \cdot 1}

\frac{- 10}{2 \cdot 1} = - 5

x = - 5

The solution to the quadratic equation is:

x = - 5
