Question

Find the greatest common factor of 8a3b2 and 12ab4. @Zelda

Answer 1

Well, here are your expressions right?
\[8a^3b^2 \] and \[12ab^4\]

So, do it step by step, numbers first. So what's the largest number that is both a factor of 8 and 12? (4), Then, you do the (a)'s, look for the a's to the least power, so, a^1 = a is the least power. Finally, check for the lowest power between b^2 and b^4, which is b^2.

So you're factor is (multiply the things we found together) to get: \[4ab^2\]

Answer 2

Factor completely.

x3 + 6x2 - 4x - 24

(x+ 6)(x- 2)(x+ 2)
(x+ 2)(x- 6)(x+ 2)
(x- 6)(x+ 2)(x+ 2)
