Step-by-step explanation:
Use the FOIL method
w × 6w =
![6 {w}^{2}](https://tex.z-dn.net/?f=6%20%7Bw%7D%5E%7B2%7D%20)
w × 2z = 2wz
-7z × 6w = -42wz
-7z × 2z =
![- 14 {z}^{2}](https://tex.z-dn.net/?f=%20-%2014%20%7Bz%7D%5E%7B2%7D%20)
this simplified equals
![6 {w}^{2} - 40wz - 14 {z}^{2}](https://tex.z-dn.net/?f=6%20%7Bw%7D%5E%7B2%7D%20%20-%2040wz%20-%2014%20%7Bz%7D%5E%7B2%7D%20)
first term: 6w^2
second term: -40wz
third term: -14z^2
<span>C(t)=t^2+t+7
To get this answer you must add the two equation together, and add together the like terms (Ex. 3t-2t and 5+2)</span>
