Question 1199631
.


This algebraic expression is  &nbsp;&nbsp;&nbsp;&nbsp;4x + 4y.    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>


The same quantity in another form is &nbsp;&nbsp;&nbsp;&nbsp;4(x+y). &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>Another &nbsp;ANSWER</U>



I don't know which one of these two forms is &nbsp;" simplified ".  &nbsp;&nbsp;They both are quite simple.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This instruction about &nbsp;" simplified form " &nbsp;really produces unnecessary pressure on a reader.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;May be, &nbsp;the author means &nbsp;&nbsp;(x+x+x+x) + (y+y+y+y) &nbsp;&nbsp;as pre-simplified form ?
