32x4 - 2x3 + 54x
Find the greatest common factor (GCF) for each term. Let's count the number of x's. There is at least 1 x in each term. Factor the x from each term to get x*(32x3 - 2x2 + 54). Then, we will look at the coefficients 32, -2, and 54. Find the GCF for each coefficient. Turns out we get 2. So the expression is as follows:
2x*(16x3 - x2 + 27)
