after a decision is made as to what is wanted in a tree,the forester goes into the woods and tries to find a tree as near as possible to the ideal。that is the approach on superior trees。the selectionist is taking the best that nature has produced over the centuries。selection is the...
Write the quadratic polynomial in shifted form (i.e., complete the square). A) f(x) = x^2 + 6x + 1 B) f(x) = -3x^2 + 24x - 8 The quadratic x^2+1300x+1300 can be written in the form (x+b)^2+c, where b and c are c...
Repeat Steps 1 and 2 with the other zeros and add them as further factors. For instance, if the example polynomial has two more zeros, -2 and 3, both with multiplicity 1, two more factors — (x + 2) and (x – 3) — must be added to the polynomial. The final form of the poly...

Determine whether the statement is true or false. A rational expression is defined as a polynomial times a polynomial. Determine whether the statement is true or false. One of the terms in the expansion of (x - 2y)^(12) is 7920x^4y^8. ...
Sigma notation can be used to present the same information as the sum of a series in a standardized manner. Explore examples of Sigma notation, and discover the way that it reduces patterns to more conven...
Another possible reason for copying the style of a more senior mathematician is that one does not yet have the self-confidence to write in one’s own style and voice. While this is justifiable to some extent when one is just starting one’s career, it becomes less excusable as one continu...
