Answer 6

16 - x2 would be factored into (4-x) and (4+x) To double-check, multiply the factors: (4-x)(4+x) = 16 + 4x - 4x -x2 = 16 - x2

Answer 7

To factor 64a2 - 81, first step is to find a way to split 64a2 into two numbers. Next step is two split 81 into two numbers. Final step is to calculate the answer based on the first two steps. For example: 1. 8a * 8a = 64a2 2. 8a * -9 = -72a (outer) and 8a * 9 = 72 (inner) 3. -9 * 9 = -81 FINAL ANSWER : 64a2 - 72 + 72 - 81 = 64a2 - 81
