Question

1. (8-5x)(9-5x)
2. (2a-5)(2a-9)
3. (15+6p)(8-4p)
4. (6p-9q(6p+9q)
5. (8p+4q)(6p+7q) . bagaimana caranya , tolong yaaa

Answer 1

1. 72-40x-45x+25x² = 72-85x+25x²
2. 4a²-18a-10a+45 = 4a²-28a+45
3. 120-60p+48p-24p² =120-12p-24p²
4. 36p²+54pq-54pq-81q² =36p²-81q²
5. 48p²+56pq+24pq+28q² =48p²+80pq+29q²

Answer 2

1). (8.9)+(8.-5x)+(-5x.9)+(-5x.-5x) =
72+(-40x)+( -45x)+25x^ = 25x^-95x+72



2). (2a.2a)+(2a.-9)+(-5.2a)+(-5.-9)

dikalikan pelangi. (.)=kali
3). (15.8)+(15.-4p)+(6p.8)+(6p.-4p)
4). (6p.6p)+(6p.9q)+(-9q.6p)+(-9q.9q)
5). (8p.6p)+(8p.7q)+(4q.6p)+(4q.7q)
