x^{2} - 7 = - 6 x

x = 1, x = - 7

Solution steps

x^{2} - 7 = - 6 x

Move

6 x

to the left side

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

Write in the standard form

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

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, 9 x^{2} + y^{2} + 90 x - 12 y + 261 = 0

6 x^{2} = 48 x

(k - 1) x^{2} + 2 x + (1 - k) = 0

2 x^{2} - 6 x + 1 = 0

x^{2} + 0.5 x - 0.5 = 0
