Answer:
<em>The greatest number of song he can practice in a week is 2.</em>
Step-by-step explanation:
Suppose, the greatest number of song he can practice in a week is 
He practices each song for 
hours. So, the total time required for practicing number of songs 
hours.
Given that, he practices his guitar for 9 hours each week.
So, the equation will be......
<em>(Rounded as the greatest whole number)</em>
Thus, the greatest number of song he can practice in a week is 2.
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
<span>(DOS= difference of two squares, PST=perfect square trinomial </span>
<span>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.</span>
