Question

16 (2l – 3m)2 - 12(3m – 21) who will the correct answer will be marked as brainliest and will be rated 5 star!​

Answer 1

Step-by-step explanation:

Ans :-(336-48)2-36m+252

672-96m-36m+252

672+252-96m-36m

924-132m=0

-132m=-924

m=924÷132

m=7

Answer 2

Answer:

4(8l-12m+3)(2l-3m)

Step-by-step explanation:

16(21-3m)*2-12(3m-21)

=16(21-3m)*2 + 12(21-3m) [(3m-2l)=--(2l-3m)]

= 16(2l-3m) + 12](2l-3m) [Taking (2l-3m) as the common factor]

= 4[4(2l-3m) + 3] (2l-3m) Taking 4 as the common factor of [16(2l-3m)+12]

=4(8l-12m+3)(2l-3m)
