Given

Divide it by (x+1) using synthetic division, as shown below
The green line is a minus sign.
Thus,

Therefore, since the remainder is different than zero, (x+1) is not a factor of 4x^2+2x-5
I am not to sure but I would go for B. identity.
-2 and -2 Two negatives added equal a positive.............. . . .. . . . . . .
Answer:
all equation has a solution
Answer: 38 over 49 can be written as 38/49. When divided, you will get 0.77551020408. It takes lots of regrouping, but it ends eventually.
If you are reducing it as a fraction, it is not possible because there is no other number to reduce it, so it will be in it's simplest form already.
