Verified answer

1 is the answer.

Since, the mathematical equation is in its fractional form--a division--and is consisting of similar factors; then,

when:

a. we divide 2x + 3 by 2x + 3, the answer will be 1;

b. we divide x + 1 by x + 1, the answer will be one as well.

Generally, when divide a number by itself, the answer will be equated to one (1). For example, when we divide 1 by 1, the answer will be 1; 9 ÷ 9 = 1. However, when we divide 0 by itself, then the answer will be undefined or infinite solution.

In the mathematical equation above, as we divided them by their pair, we are now multiplying them; where:

Hence, one (1) is the answer to your equation.
