+950 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 terms out. We get that
x3(x2+tx)=x5+tx4
There is no x^2 in this polynomial.
However, it is possible if t has a x^-2 to it, then we get x^2.
Other than that, no other terms work.
Thanks! :)
