Answer
$x^2-3x+4$
$quadratic$ $trinomial$
Work Step by Step
This is the problem.
$x^2+4-3x$
We need to put the polynomial is standard form, then name the polynomial.
$x^2$ has the highest degree, so it will go first, followed by $-3x$ and $4$.
$x^2-3x+4$ is the polynomial's standard form.
Now, we need to name the polynomial. It is quadratic because its highest degree is $2$, and it is a trinomial because it has three terms.
Therefore, it is a quadratic trinomial.
