Is there a picture to go along with your question?
According to the task you give: <span>The binomial (y − 2) is a factor of y2 − 10y + 16. The other factor is C- (y-8) reffering to the major rules identifying the factors of binimials. By knowing factors you can make the factored form then by multiplying them.</span>
1 1/2 = 3 / 2 = 6 / 4 miles;
Because 9 > 6, we have 9 / 4 > 6 /4;
9 /4 miles is longer than 1 1 /2miles;
