  2. Cancelling out - Wikipedia

    en.wikipedia.org/wiki/Cancelling_out

    For example, a fraction is put in lowest terms by cancelling out the common factors of the numerator and the denominator. [2] As another example, if a×b=a×c, then the multiplicative term a can be canceled out if a≠0, resulting in the equivalent expression b=c; this is equivalent to dividing through by a.

    Arial is probably the best to use because its simple lines come out well when the image is rasterised. It’s better not to use annotation to give a diagram a title. Put the diagram inside a table and use the table caption to do it. That way it can easily be changed. Do not be tempted to use the WordArt button next to the text button. WordArt ...

    English: A diagram demonstrating endodontic therapy (colloquially known as a root canal) on unhealthy or injured tooth: first drilling and cleaning, then filing with an endofile, and finally adding the rubber filling and crown.

    is the order of the denominator polynomial, and a n {\displaystyle a_{n}} is the n {\displaystyle n} th coefficient of the denominator polynomial. Either M {\displaystyle M} or N {\displaystyle N} or both may be zero, but in real systems, it should be the case that M ≤ N {\displaystyle M\leq N} ; otherwise the gain would be unbounded at high ...

  7. Clearing denominators - Wikipedia

    en.wikipedia.org/wiki/Clearing_denominators

    The first step is to determine a common denominator D of these fractions – preferably the least common denominator, which is the least common multiple of the Q i. This means that each Q i is a factor of D, so D = R i Q i for some expression R i that is not a fraction. Then

  8. Root canal - Wikipedia

    en.wikipedia.org/wiki/Root_canal

    An unusual root canal shape, complex branching (especially the existence of horizontal branches), and multiple root canals are considered as the main causes of root canal treatment failures. (e.g. If a secondary root canal goes unnoticed by the dentist and is not cleaned and sealed, it will remain infected, causing the root canal therapy to fail).

  9. Extraneous and missing solutions - Wikipedia

    To begin solving, we multiply each side of the equation by the least common denominator of all the fractions contained in the equation. In this case, the least common denominator is () (+). After performing these operations, the fractions are eliminated, and the equation becomes:
