C is the correct answer :-)
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put
0.6
x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]
I'm sorry if it was confusing, I hope it helped!
Differences:
If the a≠1, then instead of finding two numbers that when multiplied equal c and when added equal b (which is the a=1 situation), you are looking for two numbers which when multiplied equal ac and add up to be b.
When finding the two numbers for a≠1, you cannot just plug the two numbers into (x+__)(x+__), you have to extend the b term into those two numbers.
After extending the b term into the two terms, you then have to group them and take out the GCF's unlike in an a=1 situation.
Similarities:
The first step for both is finding two terms which equal b if added.
Once factored, you have to set the factored sections to zero if you wish to find the solutions.
Before finding the two terms which equal b if added, you should take out any GCF's from the overall equation.
