Which costs less: a $52 jacket at 15% off or a $56 dollar jacket at 20% off? How much less?

The $52 jacket by 60(0.60) cents.

Step-by-step explanation:

To find how much percent off is each item. We would need to multiply 52 by 0.85 and 56 by 0.80. The work is below:

52*0.85=44.2

56*0.80=44.8

We can say that the $52 jacket costs less than the $56 jacket by a difference of 60(0.60) cents.

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
