Answer 2

$36a^2b^2 -12a^2b -6a^2b+18ab^3$ is the required LCM

Solution:

Given that,

We have to find the lcm of [ 2a + b x 3b -1 ] and [ 2a x 3b​ ]

step 1 :  

multiply two numbers

$(2a + b \times 3 b - 1) \times (2a \times 3b)\\\\(6ab-2a+3b^2-b) \times (2a \times 3b)\\\\6ab\left(3b^2+6ab-b-2a\right) \\\\36a^2b^2 -12a^2b -6a^2b+18ab^3$

Thus the LCM is found
