Question

[(p/8)+(3q/4)][(p/8)+(3q/4)]
​

Answer 1

Answer:

$( \frac{p}{8} + \frac{3q}{4} )( \frac{p}{8} + \frac{3q}{4} ) \\ = {( \frac{p}{8} + \frac{3q}{4} )}^{2} \\ = {( \frac{p}{8} )}^{2} + {( \frac{3q}{4} )}^{2} + 2 \times \frac{p}{8} \times \frac{3q}{4} \\ = \frac{ {p}^{2} }{64} + \frac{ {9q}^{2} }{16} + \frac{3pq}{16}$
