\[(3a^3-5b^3)+?a^3+?b^3=(a^3+b^3\]
OpenStudy (decarr432):
I think the answer it
-3a^3
5b^3
zepdrix (zepdrix):
What are the coefficients on the right? :)
\(\large\rm a^3=?~~~0a^3\)
What is the magical number that they're hiding from us?
Is it a zero?
OpenStudy (alivejeremy):
OpenStudy (decarr432):
I have to find two numbers one for a and one for b that make the equation true
to equal (a^3b^3)

+
OpenStudy (alivejeremy):
thats the answer
zepdrix (zepdrix):
I'm just trying to get you to realize how many a^3 are on the right side of the equation.
OpenStudy (decarr432):
yeah 0 for a and b
zepdrix (zepdrix):
No no no.
0apples is just 0, I wouldn't even have to write the apples.
When I write the word "apple", that implies ONE apple, yes?
When I don't write a number next to it, it's an invisible 1,
not an invisible 0 :)

So you have 1a^3 and 1b^3 on the right side of your equation.
OpenStudy (decarr432):
okay I see now the answer you be
a=-2
b=+6
OpenStudy (decarr432):
was just one off
zepdrix (zepdrix):
Ahh there we go! :)
OpenStudy (decarr432):
This is why you are the best!
