WebOften, an equation can look difficult to solve, but it can often be quite simple if you can see how to reduce it. A common example, a quartic of the form ax^4 + bx^2 + c = 0, ax4 + bx2 +c = 0, can be made much simpler by the substitution u = x^2. u = x2. So the equation becomes au^2+ bu + c = 0, au2 +bu+c = 0, a quadratic, which of course is ... WebWe can factor a difference of fourth powers (and higher powers) by treating each term as the square of another base, using the power to a power rule. For example, to factor x4 - y4, we treat x4 as (x2)2 and y4 as (y2)2. Thus, x4 - y4 = (x2)2 - (y2)2 = (x2 + y2) (x2 - y2) = (x2 + y2) (x + y) (x - y). Similarly, we can treat x6 as (x3)2 or (x2)3 ...

WebDescription. The function factor is used to encode a vector as a factor (the terms ‘category’ and ‘enumerated type’ are also used for factors). If argument ordered is TRUE, the factor levels are assumed to be ordered. For compatibility with S there is also a function ordered. contact number for northlink protea campus

So it doesn't seem to make much difference. $\endgroup$ – contact number for nhsbsa
