x^{2} - 6 x = 91

x = 13, x = - 7

Solution steps

x^{2} - 6 x = 91

Move

91

to the left side

x^{2} - 6 x - 91 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot ( - 91 )}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot (- 91) = 20

x_{1, 2} = \frac{- ( - 6 ) \pm 20}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 20}{2 \cdot 1}, x_{2} = \frac{- ( - 6 ) - 20}{2 \cdot 1}

x = \frac{- ( - 6 ) + 20}{2 \cdot 1} : 13

x = \frac{- ( - 6 ) - 20}{2 \cdot 1} : - 7

The solutions to the quadratic equation are:

x = 13, x = - 7

42 \cdot 42

2 x + 5 = 3 x - 45

4 x - 18 = x + 3

2 x + 8 = 4 x - 2
