you set all the equations equal to zero so
x=0
2x+1=0
2x=-1
x=-1/2
x-5=0
x=5
hope that helps

X=0
0*(0+1)*(0-5)=0
0*1*-5=0

Just equate each bracket to 0
1) x=0 or x=-1/2 or x=5

Let's see... if your looking for the value of x (which I assume you are), then that means 1 of those needs to equal 0, since it is already factored. So set each one to 0, and you should end up with the answer set x=0,-.5,5

x = 0, -1/2, and 5.
If any of the three multiplied terms = zero then the whole thing equals zero.

X has to equal zero for the equation to equal zero.
