Jawaban:
7p \times 7p = 49 {p}^{2}7p×7p=49p

10a \times 2b = 20ab10a×2b=20ab
( - 25m) \times ( - 2m) = 50 {m}^{2}(−25m)×(−2m)=50m

13ab \times 2b = 26a {b}^{2}13ab×2b=26ab
2
3(4 - 3y + 5) = 12 - 9y + 153(4−3y+5)=12−9y+15
3p(4pq + 5) = 12 {p}^{2} q + 15p3p(4pq+5)=12p

q+15p
- 2a(5a - 10b) = - 10 {a}^{2} + 20b−2a(5a−10b)=−10a

+20b
\begin{gathered}(2x - 5)(2x + 7) \\ = 4 {x}^{2} + 14x - 10x - 35 \\ = 4 {x}^{2} + 4x - 35\end{gathered}
(2x−5)(2x+7)
=4x
