Question 690523
Given: {{{2X^6 - 10X^4 + 12X^2}}}
You were right about pulling a 2X^2 out from each term but you left an X on your 6. It shold be:
{{{2X^2*(X^4 - 5X^2 + 6)}}}
Now find the factors of 6
6: 1, 2, 3, 6
Since 6 is positve, the two factors have to be both positive or both negative.
However, note that the 5X^2 is negative. That means you need at least one negative factor.
So if you have -1 + -6 = -7.
If you use -2 + -3 = -5. That fits your equation

So now the equation is:{{{2X^2*((X^2-3)*(X^2-2))}}}
or just simply {{{2X^2 * (X^2-3) * (X^2-2)}}}
