Question

Divide and write the quotient and the remainder.

(2m3 + m2 + m + 9) ÷ (2m − 1)

Sum

Solution

(2m3 + m2 + m + 9) ÷ (2m − 1)

               m2 + m + 1
`2m - 1")"overline(2m^3 + m^2+m+9)`
           2m3 - m2 
           -      +                      
                2m2 + m + 9
                2m2 - m
              -      +                  
                     2m + 9
                     2m - 1
                    -      +           
                              10

So, quotient = m2 + m + 1 and remainder = 10.

Explanation:

  1. (2m − 1) × m2 = 2m3 − m2
  2. (2m − 1) × m = 2m2 − m
  3. (2m − 1) × 1 = 2m − 1
