Find the sum of the following
81L23ml,12L75ml​

93mL 98mL

Step-by-step explanation:

First add the mL. There are 78mL, so it cannot become a liter. Then add the liters.

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
