According to the Zero Product Principle, if either of the expressions within the parenthesis is equal to zero, the entire thing will be zero. In simpler terms 0*[anything]=0
So, we have two ways to get a solution for x: 2x-1=0, and x+3=0
2x-1=0 +1 both sides
2x=1 /2 both sides
x=1/2
x+3=0 -3 both sides
x=-3
We have two solutions: x=1/2, and x=-3
