Question

Tolong pakai cara!! yg di bulatin saja yg genapp!!

Answer 1

4a^2-12ab/2
= 2a^2-6ab

18a^2-27a/9ab
= 2a -3/b

Answer 2

6. 5r/10pr + 20qr = r/2pr + 4qr

8. x+y/ x kuadrat - y kuadrat = x+y / (x-y) (x+y) = 1/x+y

10. x+3 / x kuadrat + 7x + 12 = x+3 / (x+3) (x+4) = 1/x+4

16. 4-x / x kudrat - 16 = x-4 / (x-4) (x+4) = 1/x+4

18. x kuadrat - 36 y kuadrat/ 12y-2x = (x-6y) (x+6y)/ 2 (x-6y) = x+6y/2

20. 1- x kuadrat/ x kuadrat - 4x-5 = (x-1) (x+1) / (x+5) (x-1) = x+1/x+5
