(13y^2+12)/(y^2)=44

解答

\frac{13 y ^{2} + 12}{y ^{2}} = 44

解答

y = \frac{2 3}{31}, y = - \frac{2 3}{31}

+1

十进制

y = 0.62217 \dots, y = - 0.62217 \dots

求解步骤

\frac{13 y ^{2} + 12}{y ^{2}} = 44

在两边乘以

y^{2}

13 y^{2} + 12 = 44 y^{2}

解

13 y^{2} + 12 = 44 y^{2} : y = \frac{2 3}{31}, y = - \frac{2 3}{31}

y = \frac{2 3}{31}, y = - \frac{2 3}{31}

验证解

找到无定义的点（奇点）:

y = 0

将不在定义域的点与解相综合:

y = \frac{2 3}{31}, y = - \frac{2 3}{31}

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

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

(x^3+3x)/(3x^2+1)= 91/37

\frac{x ^{3} + 3 x}{3 x ^{2} + 1} = \frac{91}{37}

(1/(3*2x))^4= 1/16

(\frac{1}{3 \cdot 2 x})^{4} = \frac{1}{16}

\frac{4}{y} = 2

1/m+1/((m+1))= 5/((2m+2))

\frac{1}{m} + \frac{1}{( m + 1 )} = \frac{5}{( 2 m + 2 )}
