Answer: Option d. [tex]15x^3[/tex] is right.
Explanation: For determining all the term in the shaded reason we must divide [tex]15x^3+x^2-3x+2[/tex] by [tex]3x-2[/tex]
since 3x-2=0 then x=2/3 and 2/3 is the root of the [tex]15x^3+x^2-3x+2[/tex] because [tex]15x^3+x^2-3x+2=0[/tex] at 2/3 then it will completely divided by 3x-2
So, we can right, [tex]15x^3+x^2-3x+2=( 5x^2-3x+1)(3x-2)[/tex]
after comparing this to the shaded reason in first row we will get 5x^2, -3x, and 1 .
Thus, option d .[tex]5 x^2[/tex] will be right.
