prove that

4x-5 is a factor of 36x square+29x-20

Dividing 36x2+29x-20 by 4x-5 using long division method we get;             9x+7444x-5) 36x2+29x-20             36x2-45x                           74x-20                            74x-3704                                     2904Since 36x2+29x-20 is not perfectly divisible by 4x-5. Therefore it is not factor of given polynomial.
