(x^2-(17x))/(4+1)=0

解

\frac{x ^{2} - ( 17 x )}{4 + 1} = 0

解

x = 17, x = 0

解答ステップ

\frac{x ^{2} - ( 17 x )}{4 + 1} = 0

簡素化

4 + 1 : 5

\frac{x ^{2} - ( 17 x )}{5} = 0

以下で両辺を乗じる:

5

x^{2} - 17 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 17 ) \pm ( - 17 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 17)^{2} - 4 \cdot 1 \cdot 0 = 17

x_{1, 2} = \frac{- ( - 17 ) \pm 17}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - 17 ) + 17}{2 \cdot 1}, x_{2} = \frac{- ( - 17 ) - 17}{2 \cdot 1}

x = \frac{- ( - 17 ) + 17}{2 \cdot 1} : 17

x = \frac{- ( - 17 ) - 17}{2 \cdot 1} : 0

二次equationの解:

x = 17, x = 0

2 p^{2} + k^{3} = 15

(x)=-5(x+20)*(x-80)

(x) = - 5 (x + 20) \cdot (x - 80)

solvefor x,x^2+y^2+xy=192

so l v e f or x, x^{2} + y^{2} + x y = 192

(16x)^2+(9x)^2=43^2

(16 x)^{2} + (9 x)^{2} = 4 3^{2}

solvefor x,ln(y)-1/(y^2)=(x^2)/2+c

so l v e f or x, ln (y) - \frac{1}{y ^{2}} = \frac{x ^{2}}{2} + c
