John buys a new motorcycle for $1,420.00 and a helmet for $75.00. if there is an 8% sales tax, how much will john pay when purchasing the motorcycle and helmet?

true? is that what you're asking or do you mean something else?

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
