Math vocabularySummary the principle of solving the inequalityAlthough we will understand how to solve the inequality, but in fact, the examination takes place by using the above multiplication table results.Quite a lot, so introduction the principles of:Principle.1. make either side of this inequality is zero.2. separate the multiplication factor as a parenthesis, or divide it (if it is high, might need to use synthetic Division to).3. If a positive factor which ensures that, drop (if you are not sure, you should check after the drop.)4. bring up the crisis (the opposite factor, as described later in this topic) to write a number of.5. If any part of the diploma, so x is positive, place a plus sign remove switch by starting from the right side first.Caution1. do not attempt to move the above variables by multiplying or dividing a negative number to multiply, because leading a division or to make.Back side of the inequality2. Please keep in mind, it is zero, so the question comes from must be always open range.
