I can try but I can't promise I know the answer

Do you know how to factor by grouping?

whpalmer4 · Answer

$$x^3+10x^2-9x-90$$Group each pair of terms:
$$(x^3+10x^2)-(9x+90)$$Note well that I factored out a -1 so the -90 becomes 90 inside the group
Now, can you factor each of the two groups?  What do you get?

whpalmer4 · Answer

No.  What are the common factors of $x^3$ and $10x^2$?

You're just adding and subtracting here, how could you get $x^5$?!?

whpalmer4 · Answer

What are the common factors of $x^3$ and $10x^2$?

$x^3= x*x*x$ and $10x^2 = 10*x*x$

What can you factor out of both of those quantities?

If it's getting complicated, it's only because you're inventing some new mathematics here :-)
