x^{2} + 9 x + 50 = 30

x = - 4, x = - 5

Solution steps

x^{2} + 9 x + 50 = 30

Move

30

to the left side

x^{2} + 9 x + 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 1 \cdot 20}{2 \cdot 1}

9^{2} - 4 \cdot 1 \cdot 20 = 1

x_{1, 2} = \frac{- 9 \pm 1}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 9 + 1}{2 \cdot 1}, x_{2} = \frac{- 9 - 1}{2 \cdot 1}

x = \frac{- 9 + 1}{2 \cdot 1} : - 4

x = \frac{- 9 - 1}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = - 4, x = - 5

25 x^{2} - 225 = 0

6 x^{2} + 48 x = 0

(x + 2)^{2} + (x - 3)^{2} = (2 x - 1)^{2}

x^{2} - 31 - 2 x = - 6 - 3 x^{2} - 2 x

x^{2} + (m + 2) x + 2 m = 0
