Answer:4m^2+4m+1
Step-by-step explanation:
(2m+1)^2=(2m+1)(2m+1)
Opening brackets we have:
4m^2+2m+2m+1
Add like terms
4m^2+4m+1
Answer:
The solution is
4m² + 4m + 1
Step-by-step explanation:
Solve this: (2m+1)²
If X² = X*X
Therefore, (2m+1)² = (2m+1) x (2m+1)
Opening the bracket (2m+1) x (2m+1)
=2m*2m + 2m*1 + 1*2m + 1*1
= 4m² + 2m + 2m + 1
Collect the like terms
= 4m² + 4m + 1
From this point, the equation can't be solved further.
