Answer 1

Answer:

4a² + 9b² - 12ab/36.

Step-by-step explanation:

$[\frac{a}{3} -\frac{b}{2} ]^{2} \\=>[\frac{2a-3b}{6}] ^{2} (cross multiplication)\\=> \frac{(2a-3b)^{2} }{36} \\=> \frac{4a^{2}+9b^{2}-12ab }{36}$

Whenever the denominators will be co-primes, cross multiplication of the fractions is to be done.
