Okay, so a polynomial is any algebraic expression where no terms are divided by a variable.
00:05
So when we're asking, is a particular expression a polynomial, but you're basically trying to figure out is, is there any term that's being divided by a variable? so if i had, for example, x squared plus 9, when i asked you, is this a polynomial, you would say yes.
00:25
And the reason that it is a polynomial is because it is an algebraic expression.
00:30
There's no division by a variable.
00:33
This is 1x squared.
00:35
This is positive 9.
00:36
You're adding these two terms together.
00:39
But there's no variable on the bottoms of anything.
00:41
There's no division by a variable.
00:42
So this is definitely a yes...
