How do I use the zero-factor property?

When a quadratic( Trinomial ) is factored to two binomial : i.e.
X2 - 13X + 36 = ( X - 4 ) ( X- 9 )
To solve for their roots , zeros or X - intercept of the graph of quadratic, the value of X's that make
expression X2 - 13X + 36 =0
( X- 4 ) ( X-9 ) = 0
Here we use the law of multiplication by 0, i.e. every number multiplied by 0 results in 0.
Let one X- 4 = 0 , X =4 , then X -9 = 0 X =9.
