Answer:
2x^2+16x-66
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last)
(2x-6)(x+11)
F- 2x*x=2x^2
O-2x*11=22x
I--6*x=-6x
L--6*11=-66
2x^2+22x-6x-66
Combine like terms
2x^2+16x-66
If you're looking for a fraction:
Think of it this way, the 9 is in the 10th place. The 6 is in front of the decimal. So, it's 69/10. The 10 takes the place of the 9, the "/" is the decimal moved to the right one space.
Or
If you're looking for a mixed number:
You basically split the above fraction "69/10" up into two separate pieces. So, it's
