Question 164286
{{{-2x^3-50x}}}=GCF(other factor)

2 steps
#1 Find the GCF
#2 Find the other factor

We look for the GCF or greatest common factor.
we then divide each term by the GCF to get the 'other factor'

There are two terms {{{-2x^3}}} and -50
There is a common factor of 2 in both.
Or, you could also say that there is a common factor of -2

Since the first term starts with a NEGAtive, and it 
usually easier to factor when the 1st term is POSitive, 
we will 'factor', or 'factor out', or 'take out' a -2.
Thus, -2 is the GCF or greatest common
factor.

So far we have -2x^3-50x=-2(other factor)

To find the 'other factor' after taking out a -2 we divide
each term by -2

{{{-2x^3/-2 = x^3      -50/-2 = +25}}}


{{{-2x^3-50x=-2(x^3+25)   }}}

The problem is not prime because we were able to
factor.
