c^{2} - 2 c = 6

c = 1 + 7, c = 1 - 7

Decimal Notation

c = 3.64575 \dots, c = - 1.64575 \dots

Solution steps

c^{2} - 2 c = 6

Move

6

to the left side

c^{2} - 2 c - 6 = 0

Solve with the quadratic formula

c_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 1 \cdot ( - 6 )}{2 \cdot 1}

(- 2)^{2} - 4 \cdot 1 \cdot (- 6) = 27

c_{1, 2} = \frac{- ( - 2 ) \pm 2 7}{2 \cdot 1}

Separate the solutions

c_{1} = \frac{- ( - 2 ) + 2 7}{2 \cdot 1}, c_{2} = \frac{- ( - 2 ) - 2 7}{2 \cdot 1}

c = \frac{- ( - 2 ) + 2 7}{2 \cdot 1} : 1 + 7

c = \frac{- ( - 2 ) - 2 7}{2 \cdot 1} : 1 - 7

The solutions to the quadratic equation are:

c = 1 + 7, c = 1 - 7

v^{2} + 3 v - 18 = 10 v

x^{2} + 12 x + 1 = 0

x^{2} - 20 x = 96

x, (3 x y + 7)^{2} = 6 y

x^{2} + \frac{4}{3} x = 0
