3.5 Polynomials in the Form x2+bx+c
In this section we will multiply binomials (expand) to find they result in trinomials and factor
trinomials into two binomials. Remember: Factoring and expanding are
processes. First well look at the forward direction o

2.1 The Tangent Ratio
We name the sides of a right triangle in relation to one of its acute (less than 90)
angles. The side that is across from the right angle is the hypotenuse and it is
always the longest side. The other
