67=(v^2)/(5.7)

解

67 = \frac{v ^{2}}{5.7}

解

v = \frac{3819}{10}, v = - \frac{3819}{10}

+1

十進法表記

v = 19.54226 \dots, v = - 19.54226 \dots

解答ステップ

67 = \frac{v ^{2}}{5.7}

辺を交換する

\frac{v ^{2}}{5.7} = 67

以下で両辺を乗じる:

5.7

v^{2} = 381.9

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

v = 381.9, v = - 381.9

381.9 = \frac{3819}{10}

- 381.9 = - \frac{3819}{10}

v = \frac{3819}{10}, v = - \frac{3819}{10}

(2x+1)(x-1)=(3x-1)(x+1)

(2 x + 1) (x - 1) = (3 x - 1) (x + 1)

(3x-1)^2+1=(x+1)^2+x

(3 x - 1)^{2} + 1 = (x + 1)^{2} + x

875 x^{2} = 0

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

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

- 9 x^{2} + 11 x - 44 = 0
