... Students can describe expressions such as 3 (2 + 6) as the product of two factors: 3 and (2 + 6). The quantity (2 + 6) is viewed as one factor consisting of two terms. Terms are the parts of a sum. When the term is an explicit number, it is called a constant. When the term is a product of a number a ...

Solve Systems with Elimination (Multiplication)
... So far, we have solved systems using graphing, substitution, and elimination. These notes go one step further and show how to use ELIMINATION with multiplication. What happens when the coefficients are not the same? We multiply the equations to make them the same! You’ll see… ...

Polynomials (Chapter 4) - Core 1 Revision 1. The polynomial p(x
... The polynomials f(x) and g(x) are defined by f(x) = x3 + px2 – x + 5 g(x) = x3 – x2 + px +1 where p is a constant. When f(x) and g(x) are divided by x – 2, the remainder is R in each case. Find the values of p and R (Total 5 marks) ...
