Question

factor.
25 - 10u

Explanation:

Step1: Identify the GCF

Find the greatest common factor (GCF) of 25 and 10. The factors of 25 are 1, 5, 25; the factors of 10 are 1, 2, 5, 10. The GCF is 5.

Step2: Factor out the GCF

Factor out 5 from each term: \(25 - 10u = 5\times5 - 5\times2u\)

Step3: Apply distributive property

Using the distributive property \(a\times c - b\times c=(a - b)\times c\), we get \(5(5 - 2u)\)

Answer:

\(5(5 - 2u)\)
