In finding the roots of an equation with degree greater than 1, what have you noticed about the number of roots? Can you recall a principle that supports this?
Polynomial Equation:
In finding the roots of an equation whose degree is greater than 1, the number of roots of such equation is based on the highest degree of the exponent it contain. This is based on the principle that, "every polynomial equation of degree n has at most n real roots" which is a consequence of the Fundamental Theorem of Algebra.
Definition:
A polynomial equation is any polynomial equated to zero.
Examples:
- x - 2 = 0
- x² + 2x + 5 = 0
- 5x + 1 = 0
- x³ - 2x² - 4x + 8 = 0
- x(x - 4) = 0
Explanation:
x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree.
x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree.
5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree.
x³ - 2x² - 4x + 8 = 0 have 3 roots since its highest degree is 3.
x(x - 4) = 0 have 2 roots because it is a polynomial equation of the second degree.
