Expand the binomial.. \((x+3)^2\) Do you know how to do that..?

OpenStudy (anonymous):

Like distribute it?...

OpenStudy (igreen):

\((x+3^2) \rightarrow (x+3)(x+3)\)

OpenStudy (igreen):

Can you expand it?

OpenStudy (anonymous):

Ohhhhh yeah

OpenStudy (anonymous):

also, x+x+3+3?

OpenStudy (igreen):

Sorry I meant \((x+3)^2 \rightarrow (x+3)(x+3)\)

OpenStudy (igreen):

No, they're being multiplied by each other..

OpenStudy (anonymous):

Sorry I meant x*x*3*3..

OpenStudy (anonymous):

Neither of us can type today huh?

OpenStudy (igreen):

\((x+3)(x+3)\) Expand it by first multiplying x * x, then x * 3..

OpenStudy (igreen):

Let's say we have \((x+5)(x+5)\) |dw:1404492296159:dw|
