# Math Help - Are these Alegbra Equations Prime?

1. ## Are these Alegbra Equations Prime?

1. 242y^4-200x^6
2. w^2+w-16
3. x^8-y^8
4. 4x^2+y^2
5. 6ax+3bx-2b-4a
6. 2x^2+8x+8

Thanks

And for the equation 30a^2bc+6abc-12

is the simplest form of that

6(5a^2bc+abc-2)

or can it can go simpler?

2. ## Comment

You factored out the 6 incorrectly from the last equation. Check your work please.

Also what do you mean by a prime algebra equation?

what? i factored the 6 out correctly? 6 from 30 is five. the ^2 is exponet of the a

and like is it possible to factor out the equations or are they prime like you cant factor them out anymore

3. x^8-y^8 will factor
4. 4x^2+y^2 prime
5. 6ax+3bx-2b-4a will factor

or can it can go simpler? it's as simple as I can see
...

5. oh ok thanks, and can you please explain how x^8 -y^8 can be factored?

also can

14y^2 +31y-10 be factored?

6. for this equation

6ax+3bx-2b-4a

i got (3x-2)(2a+b)

is that right?

$x^8-y^8 = (x^4+y^4)(x^4-y^4) = (x^4+y^4)(x^2+y^2)(x^2-y^2) = (x^4+y^4)(x^2+y^2)(x+y)(x-y)
$

as far as the quadratic expression $14y^2 +31y-10$ , you can tell if it can be factored if its discriminant is a perfect square number ...

$31^2 - 4(14)(-10) = 1521 = 39^2$ , so it will factor.

multiply it out and see.

i dont understand that bottom line lol sorry..?

NEVERMIND BRO THANKS THO I GOT IT !!!
