- 5 + x^{2} = - 4 x

x = 1, x = - 5

Solution steps

- 5 + x^{2} = - 4 x

Move

4 x

to the left side

- 5 + x^{2} + 4 x = 0

Write in the standard form

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

x^{2} + 4 x - 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 1 \cdot ( - 5 )}{2 \cdot 1}

4^{2} - 4 \cdot 1 \cdot (- 5) = 6

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

Separate the solutions

x_{1} = \frac{- 4 + 6}{2 \cdot 1}, x_{2} = \frac{- 4 - 6}{2 \cdot 1}

x = \frac{- 4 + 6}{2 \cdot 1} : 1

x = \frac{- 4 - 6}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 1, x = - 5

x^{2} - 5 x = x - 5

9^{2} + 4^{2} = c^{2}

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

x, \frac{( y _{2} )}{2} - \frac{( ( x + 2 ) ^{2} )}{4} = 1

x, 9 x^{2} + y^{2} - 9 z^{2} - 54 x - 4 y - 54 z + 4 = 0
