Answer:
Quadratic Trinomial
Step-by-step explanation:
Hello there!
quadratic trinomial equations look like - [tex]x^2+bx+c[/tex]
given formula [tex]n^2-7n+21[/tex] which is in the form of a quadratic trinomial
a quadratic trinomial consist of a constant, a variable to the power of 2, and a variable
Reasons why its not the other answer choices:
Linear equations do not have variables with powers therefore we can eliminate answer choice linear trinomial and linear polynomial
[tex]n^2-7n+21[/tex] is not a quadratic polynomial because a quadratic polynomial consists of a = 0
This is what a quadratic polynomial looks like
[tex]ax^2+bx+c=0[/tex]
so we can conclude that [tex]x^2+bx+c[/tex] is an example of a quadratic trinomial
