 1.1    Factoring    x2 + 2xy + y2 

Try to factor this multi-variable trinomial using trial and error 

 Found a factorization  :  (x + y)•(x + y)

 1.2    x2  +2xy  +y2  is a perfect square 

 It factors into  (x+y)•(x+y)
which is another way of writing  (x+y)2

How to recognize a perfect square trinomial:  

 • It has three terms  

 • Two of its terms are perfect squares themselves  

 • The remaining term is twice the product of the square roots of the other two terms

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
