WebA root or a zero of a polynomial are the value(s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. WebThe degree of a polynomial is the highest exponent that appears in it. The degree of x³-5x²+1 is 3. A zero of a polynomial is a value that you can plug in for x to make the whole expression equal 0. -1 is a zero of the polynomial x⁵+1, since (-1)⁵+1=0. Most polynomials have multiple different zeroes. 1 and 2 are both zeroes of x²-3x+2. oriana sup build
