x^{2} + 6 x + 1 = 8

x = 1, x = - 7

Solution steps

x^{2} + 6 x + 1 = 8

Move

8

to the left side

x^{2} + 6 x - 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 7 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 7) = 8

x_{1, 2} = \frac{- 6 \pm 8}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 6 + 8}{2 \cdot 1}, x_{2} = \frac{- 6 - 8}{2 \cdot 1}

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

x = \frac{- 6 - 8}{2 \cdot 1} : - 7

The solutions to the quadratic equation are:

x = 1, x = - 7

x^{2} + 5 = 3 x

9 x^{2} - 36 x

3 m^{2} + 15 m + 21 = 4

7 x^{2} = 4 x - 1

(5 x + 6) (4 x - 5) = (5 x + 6) (x + 10) - 42 x
