x^{2} + 6 x + 9 = 25

x = 2, x = - 8

Solution steps

x^{2} + 6 x + 9 = 25

Move

25

to the left side

x^{2} + 6 x - 16 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 16 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 16) = 10

x_{1, 2} = \frac{- 6 \pm 10}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 6 + 10}{2 \cdot 1}, x_{2} = \frac{- 6 - 10}{2 \cdot 1}

x = \frac{- 6 + 10}{2 \cdot 1} : 2

x = \frac{- 6 - 10}{2 \cdot 1} : - 8

The solutions to the quadratic equation are:

x = 2, x = - 8

5 (x - 1) + x - 8 = - x

3 x + 4 \leq 7 or \frac{5 x + 4}{2} > 7

2 x^{2} - 12 x - 80

\frac{π}{6} \cdot 2

2 x^{2} - 10 x
