7 x^{2} - 6 x = - 1

x = \frac{3 + 2}{7}, x = \frac{3 - 2}{7}

Decimal Notation

x = 0.63060 \dots, x = 0.22654 \dots

Solution steps

7 x^{2} - 6 x = - 1

Move

1

to the left side

7 x^{2} - 6 x + 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 7 \cdot 1}{2 \cdot 7}

(- 6)^{2} - 4 \cdot 7 \cdot 1 = 22

x_{1, 2} = \frac{- ( - 6 ) \pm 2 2}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 2 2}{2 \cdot 7}, x_{2} = \frac{- ( - 6 ) - 2 2}{2 \cdot 7}

x = \frac{- ( - 6 ) + 2 2}{2 \cdot 7} : \frac{3 + 2}{7}

x = \frac{- ( - 6 ) - 2 2}{2 \cdot 7} : \frac{3 - 2}{7}

The solutions to the quadratic equation are:

x = \frac{3 + 2}{7}, x = \frac{3 - 2}{7}

x, x^{2} - 4 x + y^{2} - 6 y + 22 = 0

6 x^{2} - 30 x - 450 = 0

7 x^{2} + 9 x = 0

1 - 0.5 x - 0.05 x^{2} = 0

15 = \frac{5}{3} (x + 12) 35 (x + 12)
