leva [86]

Answer:

$\implies \dfrac{ -4x+7}{2(x-2) }$

Step-by-step explanation:

The given expression to us is ,

$\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}$

Now take the LCM as ( x - 1 ) and Simplify , we have ,

$\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}$

Simplifying further , we get ,

$\implies \dfrac{ -4x+7}{2(x-2) }$

Hence the second option is correct .

What is the sum of the polynomials?

Nadya [2.5K]

For this case we have the following polynomials:

$-x ^ 2 + 9\\-3x ^ 2 - 11x + 4$

Adding the polynomials we have:

$(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)$

Rewriting we have:

$x ^ 2 (-1-3) - 11x + (9 + 4)$

Therefore, the result of the sum is:

$-4x ^ 2 - 11x + 13$

Answer:

the sum of the polynomials is:

$-4x ^ 2 - 11x + 13$
