roots

x^{2} - 18 x + 81 = 0

x = 9

Solution steps

x^{2} - 18 x + 81 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 81}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 81 = 0

x_{1, 2} = \frac{- ( - 18 ) \pm 0}{2 \cdot 1}

x = \frac{- ( - 18 )}{2 \cdot 1}

\frac{- ( - 18 )}{2 \cdot 1} = 9

x = 9

The solution to the quadratic equation is:

x = 9

6 x^{2} = - 8 x - 1

- 3 x^{2} + 4 x - 5 = 0

(x - 2)^{2} - (x - 2) = 0

6 w^{2} + w - 15 = 0

x^{2} - 2 = - \frac{7 x}{2}
