Key Insights

Step 1: Factor Out the Common Term

Notice that each term on the left-hand side contains a u. Factoring out u gives:

u(u² – 5u + 6) = 0

This is the first key step — extracting the greatest common factor.

Final Thoughts

Step 2: Factor the Quadratic Expression

Now focus on factoring the quadratic: u² – 5u + 6

Look for two numbers that multiply to 6 and add up to –5. These numbers are –2 and –3.

So,
u² – 5u + 6 = (u – 2)(u – 3)

Therefore, the equation becomes:

u(u – 2)(u – 3) = 0

Step 3: Apply the Zero Product Property

The Zero Product Property states that if a product of factors equals zero, at least one factor must be zero.
