1. satellite73 Group Title

each has a common factor of $$k$$ so you can "factor it out"

2. lovinglyhated Group Title

so i keep getting 16 but i'm not sure if thats right

3. Callisto Group Title

It's not correct. When you take out the common factor k, what is left for each term?

4. lovinglyhated Group Title

7 and 9

5. lgbasallote Group Title

remember.. $7k^2 = 7k \times k$

6. lovinglyhated Group Title

ok

7. lovinglyhated Group Title

so i have 63

8. Callisto Group Title

You cannot multiply the terms... One example: factor x^2 + 2x In this case, x is the common factor. Take it out and group the rest of the terms, that is x^2 + 2x = x (x) + 2(x) = x ( x+2) Can you try again for your question?

9. lovinglyhated Group Title

so is k(7k+9) correct

10. Callisto Group Title

Yes.
