A note on inputting your answers: use ^ to indicate power, for example:
  the quadratic "4x² + 5x – 7" should be typed as "4x^2+5x-7"
   
         
  Expand out the following brackets:    
         
Q1) a) 2 ( x + 4 ) =  
  b) 3 ( x - 5 ) =  
  c) 6 ( x + 4 ) =  
  d) 4 ( x - 2 ) =  
  e) 8 ( x - 4 ) =  
  f) 6 ( x + 12 ) =  
  g) -5 ( x + 4 ) =  
  h) -4 ( x - 6 ) =  
  i) 7 ( x - 5 ) =  
  j) -4 ( x - 8 ) =  
         
        Standard format:
Q2) a) ( x + 2 ) ( x + 3 ) =
  b) ( x + 4 ) ( x + 2 ) =
  c) ( x + 9 ) ( x + 4 ) =
  d) ( x + 6 ) ( x + 7 ) =
  e) ( x - 5 ) ( x + 3 ) =
  f) ( 2x + 8 ) ( x - 5 ) =
  g) ( 3x - 2 ) ( 4x - 3 ) =
  h) ( 4x - 6 ) ( 8x - 9 ) =
  i) ( x + 8 ) ( x - 8 ) =
  j) ( x + a ) ( x - a ) =
         
        Standard format:
Q3) a) ( x + 2 ) ( x + 3 ) ( x + 4 ) =
  b) ( x + 4 ) ( x - 2 ) ( x + 3 ) =
  c) ( x - 2 ) ( x + 2 ) ( x - 4 ) =
