if you factorise the expression 2y^2-13y, you will get (2y-7)(y-3).They will cancel out and you will finally arrive at (2y^2-13y+21)divided by 3
= 2y-7

Step-by-step explanation:
Permutation: If you are having a race with 10 people, there are 720 different ways that runners can finish the race. Since the order matters, this is a permutation.
10 x 9 x 8 =720
Combination: If you are selecting 3 members to join a club from a class of 10 students, there are 120 different clubs that can be formed. Since the order they are chosen doesn't matter, this is a combination.
(10 x 9 x 8) / 6 = 120

Given a line AB with Point C outside it.
Mark point D on the line AB. Join CD
With D as center, and any radius, draw an arc intersecting AB at E, and CD at F.
With C as center, and same radius as before, draw an arc intersecting CD at G.
Open a compass to length EF
Now,with G as center, and compass opened the same radius as before, draw an arc intersecting the previous arc at H.
Draw a line m passing through C and H.
Thus m is the line parallel to AB, and passing through point C
∴m∣∣AB
