Question

simplify :-

3/2a^2(a^2 - 1 ) + 1/4a^2(a^2 + a ) - 3/4a(a^3 - 1)​

Answer 1

Answer:

Correct option is A)

solution

Answer 2

Answer:

Step-by-step explanation:

\Put the exponent aside and simplfy the base by pulling out like factors :

6a-2b  =  2 • (3a-b)  

Remember the 4th law of exponents : (a • b)m= am• bm

Retract the exponent and apply the 4th law to the simplified base: ( 2 • (3a-b) )2 =  (2)2 • (3a-b)2
