+1493 Find $t$ if the expansion of the product of $x^3$ and $x^2 + tx$ has no $x^2$ term.
+1946 Let's multiply the polynomials and see what we get.
We have (x3)(x2+tx)
Distributing in the x^3, we find that we get the expression x5+tx4
there is actually no x^2 term, meaning t can pretty much be anything.
As long as t doesn't contain a x^-2 term, then it isn't possible there is an x^2 term.
Thanks! :)
