What is your question?
If you want to factor the formula, find the two factors for the two end terms (100 * 1 or 50 * 2 or 25 * 4, or 10 * 10) and (3 *3 or 9 * 1). What combination of these factors will cancel each other out to get 0?
Do the same with the second formula to get 14.
1. 100x^2-9
2. 8x^2+14x+6
