Explanation & Answer

I did it:)

11. (2𝑧 + 5)(2𝑧 − 5) = (2𝑧)2 − 52 = 4𝑧 2 − 25.

12. 2(3𝑥 + 7)(𝑥 − 1) = 2(3𝑥 2 + 7𝑥 − 3𝑥 − 7) = 2(3𝑥 2 + 4𝑥 − 7) = 𝟔𝒙𝟐 + 𝟖𝒙 − 𝟏𝟒.

13.
28𝑥13 + 7𝑥 9 − 14𝑥 8
= 4𝑥13−2 + 𝑥 9−2 − 2𝑥 8−2 = 𝟒𝒙𝟏𝟏 + 𝒙𝟕 − 𝟐𝒙𝟔 .
7𝑥 2
14. 𝑥 3 − 6𝑥 2 + 10𝑥 − 11 = 𝑥 2 (𝑥 − 4) + 4𝑥 2 − 6𝑥 2 + 10𝑥 − 1...
