How would you wright 2/5 in a percent form

40%

Step-by-step explanation:

2 over 5 is the same as 2 divided by 5, which equals 0.4. When changing decimals to percents you move the decimal over to the right by two spaces, so it is 40%

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
