2). (4m+12)/6 ∶ 2/(m+3) = ...
3). 4x^2 +12x/ x^2 -8x+12 : x-3/u-2= ...
tolong dijawab yaa! PR nih hrs dikumpul besok!
JAWAB
1). 9/a+4 x (a² - 16)/3
= (9/a+4) x [(a - 4)(a + 4)/3]
= 3(a - 4)
= 3a - 12
2). (4m+12)/6 ∶ 2/(m+3)
= [4(m+3)/6 × [(m+3)/2]
= (m+3)²/3
= ⅓m² + 2m + 3
3). 4x^2 +12x/ x^2 - 8x+12 : x-3/u-2= ....
wah bentuk ini rancu nih, salah tulis bisa salah hasil. tolong perbaiki penulisannya biar jangan salah tafsir, karena bisa salah jawab. Perjelas tanda apa dikali sama apa dan dibagi sama apa.
Thanks. ;)
2.(4m+12)/6 . (m+3)/2
4(m+3)/6 .(m+3)/2
4(m+3)²/12
(m²+6m+9)/3
3.4x(x+3)/(x-6)(x-2) . (x-2)/(x-3)
