Yes you are correct B is the right answer
The answer is choice C
The angles GQI and IQM combine to form the straight angle GQM which is 180 degrees. This angle is essentially a straight line. It is the line GM.
Similarities: They both are polynomials of degree 2, both of their graphs is a parabola, both have either 2 or 0 real solutions, they are both continuous functions over R
(DOS= difference of two squares, PST=perfect square trinomial
Differences: PST has three terms, whereas the difference of squares has 2. PST's factors are both the same, whereas DOS's elements are conjugates of each other. DOS can always be factored into two distinct polynomials with rational coefficients, whereas PST has two same polynomial factors.
you just have to move the decimal point 9 places to the right thats an easy trick to remember 1849900000
