-x^2+6x=9

- x^{2} + 6 x = 9

x = 3

Solution steps

- x^{2} + 6 x = 9

Move

9

to the left side

- x^{2} + 6 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 1 ) ( - 9 )}{2 ( - 1 )}

6^{2} - 4 (- 1) (- 9) = 0

x_{1, 2} = \frac{- 6 \pm 0}{2 ( - 1 )}

x = \frac{- 6}{2 ( - 1 )}

\frac{- 6}{2 ( - 1 )} = 3

x = 3

The solution to the quadratic equation is:

x = 3

75 x^{2} - 750 x + 1700 = 0

(m - 2) (m + 2) = 0

25 = (x - 3)^{2}

(x - 64)^{2} = 0

200 - 2 x = 100 + 0.2 x^{2}
