In a grocery store, a packet of chips that usually costs $12 is on sale for 30% off. What is the sale price after the discount?

3 dollars 6 cents or 3.6

Step-by-step explanation:

you need to divide the 30 percent by the twelve dollars to get your answer

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
