Question

Sederhanakanlah!
1.2x²-3x-9/4x²-9=
2.p²-p-6/9-p²=
yg bisa bantu ya.. :)

Answer 1

No 1 :
2X²-3X-9  
4X²-9

= (2X+3) (X-3) / (2X-3) (2X+3)

= X-3
  2X-3

no 2 :
= (P²-P-6 ) / (9-P²)
= (P-3) (P+2) / (3-P) (3+P)....yang bagian penyebut smua kalikan - (minus)
= (P-3) (P+2) / (P-3) (-P-3)
= (P+2) / (-P-3)
= -  P+2 
      P+3
