If the two expressions x2 â?? 11x + A and x2 â?? 14x + 2A have a common factor, find A.

• x^2+11x=-A and x^2+14x=-2A
  A=-3x
  submit A value in equations any one
  if in 1
  X^2+8x=0
  s0 x= -8
  then A=24

• x^2+11x+A and x^2+14x+2A
  so a+b = -11 and ab = A
  similarly a+d = -14 and ad = 2A
  solving the all equations we get 24. thus the value of A = 24

• from Eq.1 we get>> A=-(x^2+11x) and from 2nd we get>A=-(x^2+14x)/2.
  by comparing both we will get x=-8 or x=0,,so now put x=-8 in eQ.1..We will get
  
  ""A=24""
