Math Review of Strategies of Factoring Polynomials

Overview As a general strategy for factoring polynomials, first check to see if there are any common factors.  If there are not, check for the number of terms.  If there are two terms, it may be a difference of squares.  If there are three terms, it may be a perfect square of a binomial, or…

Math Review of Factoring More Polynomials

Overview Not all polynomial expressions are of the form x2 +ax +b, where the leading coefficient is equal to 1.  Some polynomial expressions have a coefficient that is not equal to 1, and it must be factored also.  However, the FOIL method can still be used, with one extra step to find the first product.…

Science Review of Bubbles

Overview Bubbles are usually formed when a globule of gas is suspended in a liquid.  Some common examples include the bubbles of carbon dioxide found in carbonated drinks, water vapor in boiling water, and soap bubbles. Carbonated Water Bubbles form when very small air pockets are trapped in liquids.  For example, supersaturated carbon dioxide is…

Math Review of Factoring Polynomials 150 150 Deborah

Math Review of Factoring Polynomials

Overview Factoring polynomial expressions is similar to factoring special polynomials.  The difference is that both elements do not have to be perfect squares.  It is the reverse of multiplying two binomials by using FOIL. Factoring Trinomials Trinomials of the form x2 +bx +c, when c>0 have certain aspects in common.  The coefficient of the squared…

Math Review of Factoring Special Polynomials 150 150 Deborah

Math Review of Factoring Special Polynomials

Overview Factoring polynomials in general is the reverse process of multiplying them, and then finding common factors.  However, some polynomials follow special patterns, such as the difference of two squares and trinomial squares, leading to shortcut methods of factoring. Recognizing the Difference of Two Squares In order for a polynomial to be the difference of…
