find the number of possible integral value of X.
for which this(3*X+7)^2/(X+4) give the integer value.
options:
a. 2 b. 4 c. 6 d. infinte

• after dividing the no. we get 25/X+4 as remainder.
  possible no: -29,21,-9,-5,-3,1

• (3X+7)^2/(X+4)=(3X+7)*[(3X+7)/(X+4)]=I*II
  Part I will be integer for every integral value of X,then consider Part II
  we can modify it as (3X+12-5)/(X+4)=[(3X+12)/(X+4)]-[5/(X+4)]=3-[5/(X+4)]
  so 5/(X+4) would be an integer for X value 1 and -9.
  
  So the answer will be 2

• I got 3 values of x.
  x= -3,1,21 for positive integer values of (3*X+7)^2/(X+4).
