Question 230358: Helping daughter w/ homework. Cant remember how to figure this type of prob.....'divide these polynomials'..........2x^3+7x^2+7x+5 divided by 2x+5......we got the first step with the 2x^3 and the 2x, but we are having trouble w/ the 7x^2.............not sure what to do next or how to figure it out?? The 7 is throwing us off! Thank You! Hannah & mom

     --------------------------
2x+5 |2x^3 + 7x^2 + 7x + 5






 
              x^2
     --------------------------
2x+5 |2x^3 + 7x^2 + 7x + 5
      2x^3 + 5x^2
      ------------
             2x^2 + 7x





 
              x^2 +  x
     --------------------------
2x+5 |2x^3 + 7x^2 + 7x + 5
      2x^3 + 5x^2
      ------------
             2x^2 + 7x
             2x^2 + 5x
            ------------
                    2x + 5





 
              x^2 +  x + 1
     --------------------------
2x+5 |2x^3 + 7x^2 + 7x + 5
      2x^3 + 5x^2
      ------------
             2x^2 + 7x
             2x^2 + 5x
            ------------
                    2x + 5
                    2x + 5
                   --------
