10 - x - 9 x^{2} = 0

x = - \frac{10}{9}, x = 1

Decimal Notation

x = - 1.11111 \dots, x = 1

Solution steps

10 - x - 9 x^{2} = 0

Write in the standard form

a x^{2} + b x + c = 0

- 9 x^{2} - x + 10 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 ( - 9 ) \cdot 10}{2 ( - 9 )}

(- 1)^{2} - 4 (- 9) \cdot 10 = 19

x_{1, 2} = \frac{- ( - 1 ) \pm 19}{2 ( - 9 )}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 19}{2 ( - 9 )}, x_{2} = \frac{- ( - 1 ) - 19}{2 ( - 9 )}

x = \frac{- ( - 1 ) + 19}{2 ( - 9 )} : - \frac{10}{9}

x = \frac{- ( - 1 ) - 19}{2 ( - 9 )} : 1

The solutions to the quadratic equation are:

x = - \frac{10}{9}, x = 1

x, x^{2} - 63 x y - 5 y^{2} = 8

x^{2} = 3 - 2 x

6 y^{2} - 7 y - 3 = 0

x, 5 x^{2} + 7 x y - y^{2} - x + 3 y + 6 = 0

x^{2} + 6 x - 100 = 6 x
