x^{2} - 6 x = 12

x = 3 + 21, x = 3 - 21

Decimal Notation

x = 7.58257 \dots, x = - 1.58257 \dots

Solution steps

x^{2} - 6 x = 12

Move

12

to the left side

x^{2} - 6 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot ( - 12 )}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot (- 12) = 221

x_{1, 2} = \frac{- ( - 6 ) \pm 2 21}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 2 21}{2 \cdot 1}, x_{2} = \frac{- ( - 6 ) - 2 21}{2 \cdot 1}

x = \frac{- ( - 6 ) + 2 21}{2 \cdot 1} : 3 + 21

x = \frac{- ( - 6 ) - 2 21}{2 \cdot 1} : 3 - 21

The solutions to the quadratic equation are:

x = 3 + 21, x = 3 - 21
