x^{2} - 7 x = - 2

x = \frac{7 + 41}{2}, x = \frac{7 - 41}{2}

Decimal Notation

x = 6.70156 \dots, x = 0.29843 \dots

Solution steps

x^{2} - 7 x = - 2

Move

2

to the left side

x^{2} - 7 x + 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot 2}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot 2 = 41

x_{1, 2} = \frac{- ( - 7 ) \pm 41}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 41}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 41}{2 \cdot 1}

x = \frac{- ( - 7 ) + 41}{2 \cdot 1} : \frac{7 + 41}{2}

x = \frac{- ( - 7 ) - 41}{2 \cdot 1} : \frac{7 - 41}{2}

The solutions to the quadratic equation are:

x = \frac{7 + 41}{2}, x = \frac{7 - 41}{2}
