Ahh okay, negative number is just a number, no special treatment is required. \[\large\begin{align} \color{blue}{-2}(\color{green}{3}\color{red}{+}\color{purple}{6}) ~~&=~~ (\color{blue}{-2})(\color{green}{3})\color{red}{+} (\color{blue}{-2})(\color{purple}{6})\\~\\&=~~?\end{align}\]

\[\large\begin{align} \color{blue}{-2}(\color{green}{3}\color{red}{+}\color{purple}{6}) ~~&=~~ (\color{blue}{-2})(\color{green}{3})\color{red}{+} (\color{blue}{-2})(\color{purple}{6})\\~\\&=~~(-6) \color{Red}{+} (-12)\\~\\&=~~-6-12\end{align}\]

?
ganeshie8
  • ganeshie8
nope, simply multiply numerators separately and denominators separately
CLOBBER02
  • CLOBBER02
i dont know how
ganeshie8

|dw:1433827601856:dw|

  • ganeshie8
before actually carrying out the multiplication, notice that we can cancel the common factor \(\large \color{red}{7}\) : |dw:1433827704968:dw|

  • ganeshie8
thats not right, but i really appreciate your bold attempt
CLOBBER02

thank u
ganeshie8
  • ganeshie8
to add/subtract fractions, we need to have same denominator in the bottom
CLOBBER02
  • CLOBBER02
so how do u do that
ganeshie8
  • ganeshie8
this is somewhat tricky but im sure it wont be that difficult for you, look at the bottom numbers, we have 4 and 8. they are not same, but we want them to be same... can you think of any tricks to "see" same number in the bottom ? |dw:1433828114996:dw|
