Answer:

Step-by-step explanation:
<u>Given polynomials</u>:

Factor the polynomials:
<u>Polynomial 1</u>



![\implies 3[2x(x+7)-1(x+7)]](https://tex.z-dn.net/?f=%5Cimplies%203%5B2x%28x%2B7%29-1%28x%2B7%29%5D)

<u>Polynomial 2</u>



![\implies 6[x(x+7)+2(x+7)]](https://tex.z-dn.net/?f=%5Cimplies%206%5Bx%28x%2B7%29%2B2%28x%2B7%29%5D)


The lowest common multiplier (LCM) of two polynomials a and b is the <u>smallest multiplier</u> that is <u>divisible</u> by both a and b.
Therefore, the LCM of the two polynomials is:




Not really sure i think its b not sure
