That was simple factorization. Use Zero-Product principle from that.
--
The two cartesian number lines would be h for vertical and t for horizontal number lines. h is for height of the ball. The horizontal axis intercepts for be the values for t when h is zero, or for h=0. This justifies making
and then
Multiply "both" members by to get
ZERO-PRODUCT PRINCIPLE!
Let x and y be real numbers.
If xy=0, then either x=0, or y=0, or x=y=0.
