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. (8-5x)(9-5x)=72+-40x-45x+25x^2=25x^2-85x+72
2. (2a-5)(2a-9)=4a^2-18a-10a+45=4a^2-28a+45
3. (15+6p)(8-4p)=120-60p+48p-24p^2=24p^2-12p+120
4. (6p-9q)(6p+9q)=36p^2+54pq-54pq-81q^2=36p^2-81q^2
5. (8p+4q)(6p+7q)=48p^2+56pq+24pq+28q^2=48p^2+80pq+28q^2

Answer 2

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
