thomaster (thomaster):

It's just the same as your last question

OpenStudy (anonymous):

8x+6y

thomaster (thomaster):

@ConfusedDuck Don't give direct answers.. guide people to answers. read the \(\bf\color{red}{\href{/code-of-conduct}{\underline{Code~of~Conduct}}}\)

OpenStudy (anonymous):

Ok

thomaster (thomaster):

\(\Large (4x+3y)(4x+3y)\) foil this @andrewrem12

OpenStudy (anonymous):

16x^2+12xy+16^2+12xy?

thomaster (thomaster):

Almost, where did you get the 16^2?

OpenStudy (anonymous):

whoops sorry i meant 6x^2

thomaster (thomaster):

what is 3y*3y?

OpenStudy (anonymous):

9y^2?

thomaster (thomaster):

yes :) \( \Large (4x+3y)(4x+3y)\) \( \Large 16x^2+12xy+12xy+9y^2\)

thomaster (thomaster):

last step is to combine the xy's

OpenStudy (anonymous):

24x^2y^2?

thomaster (thomaster):

Try writing your math between `\(` and `\)` :P see what happens

thomaster (thomaster):

also 12xy + 12xy is not 24x^2y^2, but just 24xy

OpenStudy (anonymous):

ah okay :) thank you

thomaster (thomaster):

no problem :) Next time when you write math, it's best to put it between `\(` and `\)` it will look a lot better
