Common Monomial
Look at every term. If k divides each of them, write ka + kb + kc = k(a + b + c). The common monomial k might be 5, or x, or 3xy. Take the highest power of each letter that truly appears in every term, and the greatest common numerical factor. Do not pull out a letter that is missing from one term.

Common Monomial
What is it?
Look at every term. If k divides each of them, write ka + kb + kc = k(a + b + c). The common monomial k might be 5, or x, or 3xy. Take the highest power of each letter that truly appears in every term, and the greatest common numerical factor. Do not pull out a letter that is missing from one term.
In simple words
- Look at every term.
- ka + kb + kc = k(a + b + c)
- common monomial
- product of factors
Important terms
Common Monomial: Look at every term. If k divides each of them, write ka + kb + kc = k(a + b + c). The common monomial k might be 5, or x, or 3xy. Take the highest power of each letter that truly appears in every term, and the greatest common numerical factor. Do not pull out a letter that is missing from one term.
What you should learn
- Define and explain common monomial.
- Apply common monomial to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Examples
- ka + kb + kc = k(a + b + c)
- common monomial
- product of factors
CORE UNDERSTANDING
Look at every term. If k divides each of them, write ka + kb + kc = k(a + b + c). The common monomial k might be 5, or x, or 3xy. Take the highest power of each letter that truly appears in every term, and the greatest common numerical factor. Do not pull out a letter that is missing from one term.
EXAM APPLICATION
State the correct term, connect it to the chapter rule or evidence, and use a clear example or calculation.

EXAM APPLICATION
State the correct term, connect it to the chapter rule or evidence, and use a clear example or calculation.
Remember
- correct term
- chapter link
- clear application
Examples
- Define first
- Show the rule or evidence
- Check units, labels, and conclusion
Remember

- common monomial
- product of factors
- keep the ideas separate
- ka + kb + kc = k(a + b + c)
- common monomial
- product of factors
- correct term
