Question

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

Answer 1

each has a common factor of \(k\) so you can "factor it out"

Answer 2

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

Answer 3

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

Answer 4

7 and 9

Answer 5

remember.. \[7k^2 = 7k \times k\]

Answer 6

ok

Answer 7

so i have 63

Answer 8

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?

Answer 9

so is k(7k+9) correct

Answer 10

Yes.

Answer 11
