Identify Common Factors: Look for common factors in pairs of terms.We will first look at the terms 2u3 and −20u2 to see if there is a common factor. We can factor out 2u2 from both terms.2u3−20u2=2u2(u−10)
Factor Out Common Factors: Look for common factors in the remaining pair of terms.Now we will look at the terms −u and +10 to see if there is a common factor. We can factor out −1 from both terms.−u+10=−1(u−10)
Combine Results: Combine the results from Step 1 and Step 2.We have factored out the common factors from each pair of terms:2u3−20u2=2u2(u−10)−u+10=−1(u−10)Now we can write the expression as:2u2(u−10)−1(u−10)
Factor Out Binomial: Factor out the common binomial factor.We can see that the binomial (u−10) is common in both terms, so we can factor it out:2u2(u−10)−1(u−10)=(u−10)(2u2−1)
