How do you find the product #(3/4k+8)^2#?
The mistake most people make is simply squaring both terms individually, so you to avoid this error, you should start by writing out the binomial like this:
This is because it was squared; if it was cubed, you'd write it thrice, and so on.
This makes it easier to visualise what exactly you're doing, therefore you're less likely to make mistakes when solving it.
Now, I don't know if you've heard of FOIL method but I'll link a video here so you can understand it better before continuing with the question: enter link description here
So, using the FOIL method, we need to multiply:
the first terms of each binomial. i.e.
Then the outer terms, i.e.
Then the inside terms, i.e
And finally the last terms, i,e,
Now you'll need to add these terms:
[you can add the terms with the same variable; but remember: you can't add
You can also now simplify the individual fractions, which is:
