In a geometry class, students are asked to describe the dimensions of a plane based on the components that create a plane. which student’s response is correct?

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
