Which expression is equivalent to (2r2+r - 1) – (3r2+48 - 5)?

BigorU [14]

Answer:

$-r^2-3r+4$

Step-by-step explanation:

The question is to simplify the expression $(2r^2+r-1)-(3r^2+4r-5)$

First, we can eliminate the 2nd parenthesis expression by changing signs of all the terms since there is a "-" sign in front. Then we add the "Like Terms". The process is shown below:

$(2r^2+r-1)-(3r^2+4r-5)\\=2r^2+r-1-3r^2-4r+5\\=-r^2-3r+4$

The first answer choices (has some typos) is correct. The correct answer is $-r^2-3r+4$
