Quadratic Trinomial

Step-by-step explanation:

Hello there!

quadratic trinomial equations look like - x^2+bx+c

given formula n^2-7n+21 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

n^2-7n+21 is not a quadratic polynomial because a quadratic polynomial consists of a = 0

This is what a quadratic polynomial looks like

ax^2+bx+c=0

so we can conclude that x^2+bx+c is an example of a quadratic trinomial
