Three hundred and nine thousand and seventeen
You have (-3 +i)/(7 + i) so you need to remove the i from the numerator, so you have to multiply by 7-i and you get
(-22 + 4i)/50 which can be simplified to
(-11 + 2i)/25
Answer:
I think its 55
Step-by-step explanation:
Answer:
A: 
B: 
Step-by-step explanation:
<u>A:</u>
Our expression is 
. We need to find some common factors. Clearly, we can see that both terms share the x² part, so we can definitely take that out:
Let's see if 96 is divisible by 6:
96 ÷ 6 = 16; since there's no remainder / the remainder is 0, we know 96 is divisible by 6, so we can also factor out 6:
Thus, the answer to part A is .
<u>B:</u>
Look at the 
part of the above factored expression. Notice that it is a difference of squares (because 
and 16 = 4²), so we can write this as:
Now take a look at the 
part. Again, it's a difference of squares because 
and 4 = 2², so rewrite that as:
Put it all together:
Thus, the answer to part B is .
