x^{2} = - 6 x - 9

x = - 3

Solution steps

x^{2} = - 6 x - 9

Move

9

to the left side

x^{2} + 9 = - 6 x

Move

6 x

to the left side

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

Write in the standard form

a x^{2} + b x + c = 0

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, f = x^{2} y

x (5 x - 1) = 6

x, y = x^{2}

x^{2} + 4 x = 7 x

x^{2} - 12 x
