QUESTION
Find the product :
1. (2m + 3)2
2. (4x + 6)2
5. (2x + 5 )3
SOLUTION ( Only for number 1 )
1. (2m + 3)2
The first step is to re-order terms so constants are on the left.
[tex] \colorbox{pink}{(2m \: + \: 3)2} \\ \colorbox{pink}{2(2m + 3)}[/tex]
The second step is to distribute.
[tex] \colorbox{pink}{2(2m + 3)} \\ \colorbox{pink}{4m + 6}[/tex]
Then you get the answer.
[tex] \colorbox{pink}{4m + 6}[/tex]
ANSWER
- 4m + 6
- 8x + 12
5. 21x
