A. 6x5y4 − y5x2 + 6
B. 17x5y + 5xy6
C. 2xy2 − 5y5
D. x2 − 2xy + 3x + 5y − 2

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

many reason,

step-by-step explanation:

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,
