Whats the numerator for the following rational expression 5/q+9/q=? /q

 The correct answer is:  " 14 " .

___________________________________________

Step-by-step explanation:

___________________________________________

Note:

 +    

  =     ;  

  only if:   ;  

   →   {since one cannot "divide by 0" .}.

_________________________________________

We are given:

 +    

         =      ;    Solve for:  " ? " ;

___________________________________________

Since the "denominators" are the same ; we can solve using the aforementioned "formula";

 →  given that:  " "  ;  

         →  {since one cannot "divide by 0" .}.

___________________________________________

→  So;  given:

    +                                             

                     =   ;

→ We can simplify the "left-hand side" of the equation               accordingly:

    →  "  +    "

                    =    

                    =   ;

___________________________________________

   →  "  =   " ;  

   →  Solve for  " ? " ;

   →  " ? " =  14 .

___________________________________________

The answer is:  " 14 " .

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

what is the rest of the question? ?
