A company uses two vans to transport workers from a free parking lot to the workplace between 7:00 and 9:00 a. m. One van has 5 more seats than the other. The smaller van makes two trips every
morning while the larger one makes only one trip. The two vans can transport 65 people, maximum.

seats in the large van. How many seats does the
larger van have?

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
