Webx2 − 9 has a degree of 2 (the largest exponent of x is 2), so there are 2 roots. Let us solve it. A root is where it is equal to zero: x2 − 9 = 0 Add 9 to both sides: x2 = +9 Then take the square root of both sides: x = ±3 So the roots are −3 and +3 And there is another interesting thing: A polynomial can be rewritten like this:
