Answer:
3xz(–4y³z⁴+5x)
Step-by-step explanation:
Look at each term. See what they have in common. Factor out the common factor, leaving the other factors, <em>divided</em><em> </em><em>by </em><em>the</em><em> </em><em>factors</em><em> </em><em>removed,</em><em> </em>within the parentheses.
12 and 15 are both multiples of 3, so factor out 3 and leave the –4 and 5.
x and x² have the common factor, x. We leave x with the 5 needed as the other factor of x². (The -4 is the other factor of -12x)
There is no y in the second term, so y can not be factored out.
z can be factored out, leaving z⁴ in the first term and 5 as the other factor in the second term in the parentheses.
