450000=-425x^2+45500x-650000

解

450000 = - 425 x^{2} + 45500 x - 650000

解

x = \frac{- 4550 0 ^{2} - 1870000000 + 45500}{850}, x = \frac{4550 0 ^{2} - 1870000000 + 45500}{850}

解答ステップ

450000 = - 425 x^{2} + 45500 x - 650000

辺を交換する

- 425 x^{2} + 45500 x - 650000 = 450000

- 425 x^{2} + 45500 x - 1100000 = 0

解くとthe二次式

x_{1, 2} = \frac{- 45500 \pm 4550 0 ^{2} - 4 ( - 425 ) ( - 1100000 )}{2 ( - 425 )}

4550 0^{2} - 4 (- 425) (- 1100000) = 4550 0^{2} - 1870000000

x_{1, 2} = \frac{- 45500 \pm 4550 0 ^{2} - 1870000000}{2 ( - 425 )}

解を分離する

x_{1} = \frac{- 45500 + 4550 0 ^{2} - 1870000000}{2 ( - 425 )}, x_{2} = \frac{- 45500 - 4550 0 ^{2} - 1870000000}{2 ( - 425 )}

x = \frac{- 45500 + 4550 0 ^{2} - 1870000000}{2 ( - 425 )} : \frac{- 4550 0 ^{2} - 1870000000 + 45500}{850}

x = \frac{- 45500 - 4550 0 ^{2} - 1870000000}{2 ( - 425 )} : \frac{4550 0 ^{2} - 1870000000 + 45500}{850}

二次equationの解:

x = \frac{- 4550 0 ^{2} - 1870000000 + 45500}{850}, x = \frac{4550 0 ^{2} - 1870000000 + 45500}{850}

8^{2} + x^{2} = 7^{2}

x^{2} = \frac{15}{16}

x^{2} = \frac{16}{121}

1/4 x^2+sqrt(2)x+2=0

\frac{1}{4} x^{2} + 2 x + 2 = 0

solvefor x,x^2y+x^2-xy^2+xy+2=0

so l v e f or x, x^{2} y + x^{2} - x y^{2} + x y + 2 = 0
