Question

Sederhanakan :
a. u²+3u/u²-9
b. u²-3u+2/2u²-2u-4
c. 6m²+8m/3m+4
d. u²-2u-3/2u²+3u+3

Answer 1

A. u^+3u/u^ - 9
   u(u+3)/(u+3)(u - 3)              ;catatan=(u+3) coret
   u/(u - 3)
b. u^ - 3u+2/2u^ - 2u - 4
    (u - 2)(u - 1)/(2u+2)(u - 2)    ;catatan=(u - 2)coret
     u - 1/2u+2
c. 6m^+8m/3m+4
   2m(3m+4)/(3m+4)               ;catatan=(3m+4)coret
   2m
Maaf,yg d gue gk ngerti
  
   

Answer 2

A. u^2 + 3u / u^2 - 9 = u(u+3)/(u-3)(u+3)= u/u-3
jadi, u^2 + 3u/u^2 - 9 = u/u-3
b. u^2 -3u+2 / 2u^2 -2u-4 = (u-1)(u-2)/2(u+1)(u-2) = u-1/2(u+1) = u-1/2u+2
jadi, u^2 -3u+2 / 2u^2 -2u-4 = u-1/2u+2
c. 6m^2 + 8m / 3m+4 = 2m(3m+4)/(3m+4) = 2m
jadi, 6m^2 + 8m / 3m+4 = 2m
