3.5x10^-2 of salt in one liter of water this is how much 2.64x10^20of liters water

Total liters of salt in liters of water is .

Step-by-step explanation:

If 1 liter of water contains amount of salt,

Then,

liters of water will contain,

should be multiplied by .

Therefore,

Total liters of salt in liters of water is .

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

72 is the answer to this problem
