Question

Hi, I've done 95% of the work for this assignment but I just need some help with explanation of the concept. I had to create a polynomial identity and matching algebraic proof and "market" it. this is what I created:

(ax + b)(x + a) = ax^2 + (a^2 + b)x + ab
And I demonstrated it by substituting in 2 for a and 3 for b.
This resulted in (2x + 3)(x + 2) = 2x^2 + 7x + 6
I demonstrated again using 8 for a and 12 for b.
(8x + 12)(x + 8) = 8x^2 + 76x + 96
The only part I need help with is marketing...i.e. what situation can this proof be applied to? Need to learn, not just answer.

Answer 1

Also, I need help proving that it works on numerical relationships...I didn't grasp that part of the lesson, so that help would be super appreciated. Medals and fans :)

Answer 2

Does a numerical relationship just mean expand on what I did - substitute coefficients for all the variables and make sure it still works?

Answer 3

This isn't working...? I got 66 = 52 when plugging in 4 for x in the first example. Crap!

Answer 4

ow snaps what math is that ?

Answer 5

algebra II...It's not usually this bad, this is just a really painful assignment.

Answer 6

im in algebr 1 sorry

Answer 7

@rockstar0765 pleeeeeease help :(

Answer 8

i have a few difficulties in this kind of stuff but i'll try to help

Answer 9

just got a little bit confused right their

Answer 10

Yes, but now I need help with the numerical relationships, too

Answer 11
