What you can do is multiply the 4 and the 10 and get 40 then add that’s to the 3 and you get 43/10 then do the same to the other fraction and the just add normally

So when you add mixed numbers, you must convert it into fractions. The four would become part of the fraction and be 43/10 and the six becomes part of the fraction which is 69/10. You can find this by multiplying 4 by the denominator and then adding it to the numerator (4 Times 10 = 40 + 3 = 43/10) and same for the other one. The answer is 112/10, simplify to 11 1/5.

They are not the same because one they dont get the same answer and one of the signs are different so it has changed the answer

Find the quotient write your answer in the simplest form !

Mrrafil [7]

Answer:

The answer is B) $\frac{2x-3}{2x+1}$

Step-by-step explanation:

Step 1: First we have to factorize the each rational expressions.

$\frac{4x^2 - 9}{6x^2 + 13x + 6}$ ÷ $\frac{4x^2 - 1}{6x^2 + x -2}$

= $\frac{(2x - 3)(2x + 3)}{(3x + 2)(2x + 3)}$ ÷ $\frac{(2x+1)(2x -1)}{(2x -1)(3x +2)}$

Now we can cancel out (2x + 3) and (2x -1) since they are common factor both in the numerator and the denominator, so we get

= $\frac{2x - 3}{3x + 2}$ ÷ $\frac{2x + 1}{3x + 2}$

Step 2: If we have fraction over fraction, we can flip the second fraction and multiply.

= $\frac{2x - 3}{3x + 2}$ x $\frac{3x + 2}{2x + 1}$

Now we can cancel out (3x + 2), so we get

= $\frac{2x-3}{2x+1}$

Thefore, the answer is B.

Thank you.
