Please help!!! Brainliest for whoever is right! What is the sum of the rational expressions below?
fenix001 [56]

Answer:

<h2>\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2}  + 3x}</h2>

Step-by-step explanation:

\frac{2x + 3}{3x}  +  \frac{x}{ x + 1}

Write all the numerators above the least common denominator

\frac{(x + 1)(2x + 3) + 3 {x}^{2} }{3x(x + 1)}

Multiply the parentheses

\frac{2 {x}^{2} + 3x + 2x + 3 + 3 {x}^{2}  }{3x(x + 1)}

Distribute 3x through the parentheses

\frac{2 {x}^{2}  + 3x + 2x + 3 + 3 {x}^{2} }{3 {x}^{2}  + 3x}

Collect like terms=\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2} + 3 x}

Hope this helps...

Good luck on your assignment...

For what value of \\(x\\) is the function \\(\\frac{1}{x-2}\\) not defined?
natima [27]

for the value of x=2 we have the function  f(x) = 1/(x-2) or f(x)=\frac{1}{x-2}  as undefined or not defined .

<u>Step-by-step explanation:</u>

<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity  .

Here we have , Function f(x) = 1/(x-2) or f(x)=\frac{1}{x-2} . We need to find a value of for which this is not defined . Let's find out:

We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e.  x-2 = 0 or x-2=0

⇒ x-2=0

⇒ x-2+2=0+2

⇒ x=2

Therefore, for the value of x=2 we have the function  f(x) = 1/(x-2) or f(x)=\frac{1}{x-2}  as undefined or not defined .
