Answer:
x^2 + 2x + 3
Step-by-step explanation:
x^2 - 2x -2 + (4x +5) -------------> x^2 +2x +3
In terms of x so it stays the same
The commutative property basically allows you to move numbers/variables/etc around and still get the same answer. You can only do this with addition and multiplication. Eg. a+b = b+a OR a x b = b x a
Distributive law<span>, in mathematics, the </span>law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. (https://www.britannica.com/topic/distributive-law)
Associative law<span>, in mathematics, either of two </span>laws relating to number operations of addition and multiplication, stated symbolically: a + (b + c) = (a + b) + c, and a(bc) = (ab)c; that is, the terms or factors may be associated in any way desired.

Here's a video that explains the basics: https://www.youtube.com/watch?v=x9hoPIMNPw4
A(b - c) = d
ab - ac = d
-ac = -ab + d
ac = ab - d
ac/a = (ab - d)/a
c = (ab - d)/a
Your answer will be A. c = (ab - d)/a. Hope this helps!
