we have the equation: (x+3)(x-2) = 0
For a product to be zero, one of the two operands needs to be a zero.
This means that either x+3 = zero or x-2 = zero
For: x+3 = zero ...................> x = -3
For: x-2 = zero ..................> x = 2
So, the two points on the graph that has a y = 0 are (-3 , 0) and (2 , 0)
