+868 Find $t$ if the expansion of the product of $x^3$ and $x^2 + tx$ has no $x^2$ term.
+1926 First, let's multiply the two terms together.
We have \(x^3(x^2+tx)\) = \(x^5 + x^4t\).
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! :)
