(4x^2-9x)/3 =0

解

\frac{4 x ^{2} - 9 x}{3} = 0

解

x = \frac{9}{4}, x = 0

+1

十進法表記

x = 2.25, x = 0

解答ステップ

\frac{4 x ^{2} - 9 x}{3} = 0

以下で両辺を乗じる:

3

4 x^{2} - 9 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 4 \cdot 0}{2 \cdot 4}

(- 9)^{2} - 4 \cdot 4 \cdot 0 = 9

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

解を分離する

x_{1} = \frac{- ( - 9 ) + 9}{2 \cdot 4}, x_{2} = \frac{- ( - 9 ) - 9}{2 \cdot 4}

x = \frac{- ( - 9 ) + 9}{2 \cdot 4} : \frac{9}{4}

x = \frac{- ( - 9 ) - 9}{2 \cdot 4} : 0

二次equationの解:

x = \frac{9}{4}, x = 0

0 = x^{2} - 10 x + 24

5(x+4)^2=2(x+1)^2-27

5 (x + 4)^{2} = 2 (x + 1)^{2} - 27

x^2-100x+2500=1152pi^2x-56700pi^2

x^{2} - 100 x + 2500 = 1152 π^{2} x - 56700 π^{2}

x^{2} - x - 21 = 0

solvefor x,16x^2+25y^2+400=0

so l v e f or x, 16 x^{2} + 25 y^{2} + 400 = 0
