Question

simplify(9y²+6y-1/3y+1) please answer me this question on paper​

Answer 1

     Answer:

Step-by-step explanation:

                 1

Simplify   —

           3

                 1

 (((9•(y2))+6y)-(—•y))+1

                 3

                    y      

 ((32y2 +  6y) -  —) +  1

                  3      

     3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  3  as the denominator :

                9y2 + 6y     (9y2 + 6y) • 3

    9y2 + 6y =  ————————  =  ——————————————

                   1               3        

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

 4.1     Pull out like factors :

  9y2 + 6y  =   3y • (3y + 2)

       4.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3y • (3y+2) • 3 - (y)     27y2 + 17y

—————————————————————  =  ——————————

          3                   3      

 (27y2 + 17y)    

 ———————————— +  1

      3          

27y2 + 17y + 3

 ——————————————
