\frac{1}{2} x^{2} - 2 x - 6 = 0

x = 6, x = - 2

Solution steps

\frac{1}{2} x^{2} - 2 x - 6 = 0

Multiply both sides by

2

x^{2} - 4 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 \cdot 1 \cdot ( - 12 )}{2 \cdot 1}

(- 4)^{2} - 4 \cdot 1 \cdot (- 12) = 8

x_{1, 2} = \frac{- ( - 4 ) \pm 8}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 8}{2 \cdot 1}, x_{2} = \frac{- ( - 4 ) - 8}{2 \cdot 1}

x = \frac{- ( - 4 ) + 8}{2 \cdot 1} : 6

x = \frac{- ( - 4 ) - 8}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

x = 6, x = - 2

y + 1 = \frac{y ^{2} - 6}{2}

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

x^{2} - 49 = (x + 7)

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

n^{2} + 14 n - 5 = 0
