Tamika has $2.50 in quarters in her pocket, including 7 state quarters. She reaches into her pocket and takes out two quarters, one at a time. What is the probability that they are both state quarters?

72 is the answer to this problem

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
