Which of the following equations would produce a parabola? Check all that apply. -5x2 + 4x - 7y + 14 = 0
0 - 2 + 6x + y2 - 8 = 0
9x2 - 12xy + 4y2 + 4x – y + 5 = 0
12x + 6y-
- 5y² + 14 = 0
2012 + 10xy - y2 + 3x - 6y + 5 = 0

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,

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.

there are no multiple choices
