- 0.1 x^{2} + 90 x = 20250

x = 450

Solution steps

- 0.1 x^{2} + 90 x = 20250

Multiply both sides by

10

- x^{2} + 900 x = 202500

Move

202500

to the left side

- x^{2} + 900 x - 202500 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 900 \pm 90 0 ^{2} - 4 ( - 1 ) ( - 202500 )}{2 ( - 1 )}

90 0^{2} - 4 (- 1) (- 202500) = 0

x_{1, 2} = \frac{- 900 \pm 0}{2 ( - 1 )}

x = \frac{- 900}{2 ( - 1 )}

\frac{- 900}{2 ( - 1 )} = 450

x = 450

The solution to the quadratic equation is:

x = 450

x^{2} - 23 x - 50

4 x^{2} = 13 x - 75

x^{2} + 10 x + 25 = 7
