Rational and Irrational Numbers - School of Computer Science
... A rational number is one that is equal to some fraction m/n where m and n are whole numbers (m positive, negative or zero; n positive or negative but non-zero). All other numbers are irrational. The word “rational” comes from “ratio” — it’s not a synonym of “logical” or “not crazy”! ASIDE: but look ...

A5 Simultaneous equations
... The elimination method If two equations are true for the same values, we can add or subtract them to give a third equation that is also true for the same values. For example, suppose 3x + y = 9 5x – y = 7 Adding these equations: 3x + y = 9 + 5x – y = 7 8x divide both sides by 8: ...

How to find zeros of f(x) when it`s in expanded form and factoring
... When we try to find zeros of a polynomial function in expanded form and factoring doesn’t seem feasible, we a) Use synthetic division! b) Use Rational Zeros Theorem, Descartes’ Rule of Signs and Boundedness Theorem as guides for numbers we need to try in synthetic division. c) The goal is to reduce ...
