We know that Dividend = Divisor * Quotient + Remainder.   ------ (1)

Here,

Dividend = 2x^3 + 4x^2 + 5x + 7

Divisor = g(x)

Quotient = 2x

Remainder = 7 - 5x.


Substitute all in (1), we get

= > 2x^3 + 4x^2 + 5x + 7 = g(x) * 2x + 7 - 5x

= > 2x^3 + 4x^2 + 5x + 7 - 7 + 5x = g(x) * 2x

= > 2x^3 + 4x^2 + 10x = g(x) * 2x

= > g(x) = (2x^3 + 4x^2 + 10x)/2x



         x^2 + 2x + 5
        -----------------------------
2x)  2x^3   +  4x^2   + 10x

       2x^3   

       --------------------------------

                      4x^2  +  10x

                      4x^2  

          ---------------------------------

                                      10x

                                      10x

          --------------------------------------

                                           0



Therefore g(x) = x^2 + 2x + 5.


Hope this helps!
