Question

9. Show that:


c. (3p + 9)2 – (3p - 9)2 = 12pq
​

Answer 1

Answer:

2(3p + 9) 2(3p - 9) = 12pq

6p + 18 × 6p - 18 = 12pq

36p^2 = 12pq

p^2 = 12pq/36

p^2 = 0.333

p = √0.333

Step-by-step explanation:

sorry this is equation sum

Answer 2

Answer:

(3p+9)2 - (3p-9)2 = 12pq

6p+18 - (6p-18) = 12pq

6p+18 - 6p+18 = 12pq

36 = 12pq

36/12 = pq

3 = pq answer
