Hi, if anyone can help me with the following questions, it would be GREATLY appreciated!
These 3 questions must be common factored:
1. 3x^4 - 27x^2 + 15x^6
2. 8x^-2 + 16x^5 - 14x^-3
3. -3(x-1)^2 - 12(x-1)^-3
THANK YOU
1. $\displaystyle 3x^4 - 27x^2 + 15x^6$
$\displaystyle (3x^2)(x^2+5x^4-9)$
2. $\displaystyle 8x^{-2} + 16x^5 - 14x-3$
$\displaystyle \frac{2(8x^{8}+4x-7)}{x^{3}}$
3. $\displaystyle -3(x-1)^{2} - 12(x-1)^{-3}$
$\displaystyle -\frac{3(x^{5}-5x^{4}+10x^{3}-10x^{2}+5x+3)}{(x-1)^{3}}$
this is my answer.
