Consider a = (x^2 -17x +71) and b = (x^2 -34x +240). case 1: let a = 1, b may be anything. x^2 -17x +71 = 1, which gives x = 7 or 10. case 2: let b =0 and a non-zero. x^2 -34x +240 = 0, gives x = 10 or 24. case 3 : let a = -1 and b = even. x^2 -17x +71 =
I think almost everyone forgetting the first line of the problem." A VAMPIRES A TOWN AND BITES TWO PERSONS EVERY NIGHT ". 1st night= 2 (bitten by original vampire) 2nd night= 2 +4(bitten by 2 persons turned vampires previous night) 3rd night= 2 +4(bitten
Molecules A and B react to produce molecule AB. If 60 mLs of 0.025 M A is added to 18 mLs of 0.175 M B, then how many moles of unreacted A or B will be left over? How many moles of AB will be produced?
the ans is 0
