It's worth pointing out that cubic equations are not so easy to solve If the equation in Example 3 were quadratic, we could use the quadratic formula, but it's
The graph suggests that the function has three zeros, one of which is x = 2 It's easy to show that f(2) = 0, but the other two zeros seem to be less

as simple as it was for quadratics remainder and factor theorems to factorise and to solve From the above examples, we saw that a polynomial
Factor theorem state with proof examples and solutions factorise the minus As mercury can see factoring the difference of two squares is pretty easy
By the definition of Gf we can do this without intro- ducing into F' two edges with a common end We thus construct a 1-factor of G' Conversely suppose G' has
the following are all examples of quadratic equations o 2 2 ? 3 ? 5 = 0 we will use the Zero Factor Theorem to solve quadratic equations
An important consequence of the Factor Theorem is that finding the zeros of a polynomial is really the same thing as factoring it into linear factors
as simple as it was for quadratics We would remainder and factor theorems to factorise and to solve From the above examples, we saw that a polynomial
It's worth pointing out that cubic equations are not so easy to solve If the equation in Example 3 were quadratic, we could use the quadratic formula, but it's cubic
It's easy to show The Factor Theorem: Suppose p is a nonzero polynomial The proof of The Factor Theorem is a consequence of what we already know
THEOREM A G is without a l-factor if and only if there is a subset S of V such that Consider any simple subset W of V We write 5 and T for the sets of vertices
and factor theorems to find factors of polynomials A26 Generally when a polynomial is divided This gives an easy way of finding the remainder when a polynomial is divided by (x – a) Examples 1 Using previous example 5)12 3)(2 ( 35 4
