(c). With this polynomial we have four terms and the zeroes here are, Now, weâve got some terminology to get out of the way. If r is a zero of a polynomial and the exponent on the term that produced the root is k then we say that r has multiplicity k. Zeroes with a multiplicity of 1 are often called simple zeroes. For example, the polynomial will have one zero, , and its multiplicity is 2.
We'll start by looking at changes in matter, but as you'll see, it is not possible to talk about changes in matter without talking about adding or releasing energy. Matter can be changed two ways, physically and chemically. Let's discuss Physical changes first. Physical changes. Physical changes occur when matter changes from one state of matter to another state of matter by adding or losing thermal energy. In a physical change of state matter retains its original identity, it just changes the state of matter it is in. For example: Imagine a beaker of ice sitting on a warm hot plate. As you watch the ice, this solid water makes a physical change of state to liquid water.
Typically, a chemical change is irreversible. In contrast, physical changes do not form new products and are reversible.This is a list of more than 10 examples of chemical changes. 1  rusting of iron. 2  combustion (burning) of wood.3  metabolism of food in the body. 4  mixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH). 5  cooking an egg.n contrast, physical changes do not form new products and are reversible.This is a list of more than 10 examples of chemical changes. 1  rusting of iron. 2  combustion (burning) of wood. 3  metabolism of food in the body.
