x^{2} + 6 x + 15 = 6

x = - 3

Solution steps

x^{2} + 6 x + 15 = 6

Move

6

to the left side

x^{2} + 6 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot 9 = 0

x_{1, 2} = \frac{- 6 \pm 0}{2 \cdot 1}

x = \frac{- 6}{2 \cdot 1}

\frac{- 6}{2 \cdot 1} = - 3

x = - 3

The solution to the quadratic equation is:

x = - 3

x^{2} - x - 30 = 0

x, f (x - 2) = 3 x^{2} - 2

x, x^{2} = 16

(x^{2} - x + 30) = 0

(4 - x) x + x = 2
