What multiplication expression is equal to 1/2 divided by 4/5?

1/2 times 5/4

Step-by-step explanation:

This is because of the reciprocal. When you divide a number by another you can flip the other and multiply it if it is in fraction form. Example:

10/(1/2)=10*2

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

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
