+900 Find $t$ if the expansion of the product of $x^3$ and $x^2 + tx$ has no $x^2$ term.
+1950 First, let's multiply the two terms together.
We have x3(x2+tx) = x5+x4t.
In general, I think t could be any number as long as it doesn't have an x with power above 21.
I hope I answered your question!
Thanks! :)
