-x^2+11x-24=0

解

- x^{2} + 11 x - 24 = 0

解

x = 3, x = 8

解答ステップ

- x^{2} + 11 x - 24 = 0

解くとthe二次式

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 ( - 1 ) ( - 24 )}{2 ( - 1 )}

1 1^{2} - 4 (- 1) (- 24) = 5

x_{1, 2} = \frac{- 11 \pm 5}{2 ( - 1 )}

解を分離する

x_{1} = \frac{- 11 + 5}{2 ( - 1 )}, x_{2} = \frac{- 11 - 5}{2 ( - 1 )}

x = \frac{- 11 + 5}{2 ( - 1 )} : 3

x = \frac{- 11 - 5}{2 ( - 1 )} : 8

二次equationの解:

x = 3, x = 8

-(550x^2)/2+(2000(x-4)^2)/2+3200=0

- \frac{550 x ^{2}}{2} + \frac{2000 ( x - 4 ) ^{2}}{2} + 3200 = 0

- 7 a^{5} n^{2} = 2

solvefor x,x^2+4xy+4y^2-3x+4y-10=0

so l v e f or x, x^{2} + 4 x y + 4 y^{2} - 3 x + 4 y - 10 = 0

x(x+1)-(4-x)(x+1)=6(4-x)

x (x + 1) - (4 - x) (x + 1) = 6 (4 - x)

solvefor y,z^2=x^2+y^2

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