Respuesta :
First you take out x since every variable has it.
x(x^2-9x+20)
Then you break it up to find out what makes 20 when multiplied but -9 when added.
x(x-5)(x-4)
So the 0s would be 0,5,4
x(x^2-9x+20)
Then you break it up to find out what makes 20 when multiplied but -9 when added.
x(x-5)(x-4)
So the 0s would be 0,5,4
