## lovinglyhated 2 years ago i'm stuck i need help factoring out this> 7k^2+9k

1. satellite73

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

2. lovinglyhated

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

3. Callisto

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

4. lovinglyhated

7 and 9

5. lgbasallote

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

6. lovinglyhated

ok

7. lovinglyhated

so i have 63

8. Callisto

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

so is k(7k+9) correct

10. Callisto

Yes.
