Answer 1

Answer:

2 (i) { We find the co-efficient by removing that constant or variable and looking at the rest of the expression }  x in -2xy = -2y

2(ii).  xy₂ in -7xy₂ = -7

2(iii).  x in-xy₂ =  -y₂

3(i).  1 ((Because 1*x*y =xy))

3(ii).  -3((Remove all variables [ not signs << - or + >> ] ))

3(iii).  -9

3(iv). -5

4(i) -2 * -9

4(ii)2 * -5 + 6

4(iii) -5/2
