Dividing a polynomial by an integer or an expression is really just another way of simplifying. There isn’t actually anything new to learn: you just need to be able to simplify numbers (like 20/15 simplifies down to 4/3) and know how to divide with indices (when you divide with indices, you subtract the powers. So x^7 / x^3 = x^4). To divide a polynomial by a number (or integer), there are 3 simple steps to follow: (1) Rewrite the question as a fraction. (2) Split the problem into pieces by writing each term over the denominator. (3) Finish by simplifying each term. EXAMPLE: (8a + 10b - 14) / 2. (1) Rewrite as a fraction (8a + 10b - 14) / 2 (2) Split it up 8a/2 + 10b/2 - 14/2. (3) 8a divided by 2 is 4a. 10b divided by 2 is 5b. And 14 divided by 2 is 7. ANSWER: 4a + 5b - 7. Simple!! We follow the same 3 simple steps for dividing by monomials too (remember that a monomial is an expression with just one variable in).

In this video we will learn how Alfred Wegener proposed a theory in 1912 that the great continents of the Earth had drifted over geological time and were once all joined together in a giant land mass we now call Pangaea. His idea was based on the way present day continents fit neatly together, and
In this video we are will look at mitosis, including the names of the key stages: interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Mitosis is the process of cell division that produces identical copies of cells, and is involved in growth, cell repair and asexual reproduction.
Photosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light intensity, carbon dioxide concentration and also temperature. These factors are called limiting fact
