x (x - 6) = 7

x = 7, x = - 1

Solution steps

x (x - 6) = 7

Expand

x (x - 6) : x^{2} - 6 x

x^{2} - 6 x = 7

Move

7

to the left side

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} : 7

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

The solutions to the quadratic equation are:

x = 7, x = - 1

x + 15 = \frac{( x - 9 ) ^{2}}{2}

2 a^{2} - 5 a + 5 = 0

7 - 4 x - x^{2}

r^{2} + 2 r + 26 = 0

24 x^{2} - 8 = 0
