2a-[3{2(4a-b)-5(a+2b)}+4a]
Answers
Step-by-step explanation:
2a-[3{8a-2b-5a-10b}+4a]
=2a-[3{3a-12b}+4a]
=2a[9a-36b+4a]
=2a(13a-36b)
=26a^2-72ab
The answer is -11a + 36b
GIVEN
Mathematical operation
2a-[3{2(4a-b)-5(a+2b)}+4a
TO FIND
To simplify the given expression
SOLUTION
We can simply solve the above problem as follows;
We are given a mathematical term
2a-[3{2(4a-b)-5(a+2b)}+4a]
Solving the parenthesis
2a-[3{(8a-2b)-(5a+10b)}+4a]
2a - [3(8a-2b - 5a - 10b) + 4a]
Combining the like terms in the parenthesis
2a - [3( 8a-5a-2b-10b) +4a]
Substracting 5a from 8a
2a-[3(3a-2b-10b)+4a]
Adding -2b to -10b
2a-[3(3a-12b)+4a]
Multiplying the inner parenthesis by 3
2a - [(9a - 36b)+ 4a]
Adding 9a to 4a
2a - [13a - 36 b ]
= 2a - 13a + 36b
Adding 2a to -13a
-11a + 36b
Hence, The answer is -11a + 36b
