Question

Tolong jawab nomor 10

Answer 1

A. x+2 dibagi x- empat
b.2x + empat dibagi x + tiga
c.2x-5 dibagi x-5

Answer 2

A.  x* + 6 x + 8 = ( X + 2 ) ( x + 4 )
     x* - 16 = ( x + 4 ) ( x - 4 )
     ( x +2 ) / ( x - 4 )

B. 2x* - 8 = 2 ( x* - 4 ) = 2 ( x + 2 ) ( x - 2 )
    x* + x - 6 = ( x - 2 ) ( x + 3 )
   = 2 ( x + 2 ) / ( x + 3 )

C. 4x* - 4x - 15 = 4x* + 6x -10x - 15 = 2x (2x + 3 ) -5 (2x + 3 )
                                                     = (2x - 5) (2x + 3 )
    2x* + x -3 = 2x* - 2x + 3x - 3 = 2x (x - 1) + 3 (x - 1)
                                               =(2x + 3) ( x - 1)
    
     (2x - 5) (2x + 3) / ( 2x + 3) ( x - 1)
  = (2x - 5) / (x - 1)
