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

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

Decimal

x = 1, x = - 0.9

Solution steps

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

Refine

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

Solve with the quadratic formula

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

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

x_{1, 2} = \frac{- ( - 1 ) \pm 19}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 19}{2 \cdot 10}, x_{2} = \frac{- ( - 1 ) - 19}{2 \cdot 10}

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

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

The solutions to the quadratic equation are:

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

x, \frac{( y _{2} )}{2} - \frac{( ( x + 2 ) ^{2} )}{4} = 1

x, 9 x^{2} + y^{2} - 9 z^{2} - 54 x - 4 y - 54 z + 4 = 0

3 x^{2} + 11 x - 7 = 0

A = x^{2} + x - 2

8 x^{2} - 28 x - 60 = 0
