<h2>Answer:</h2>
The product of the given expression is:
We are asked to find the product if two quadratic expressions which are given in terms of variable "m".
The expression is given by:
We could observe that the expression is given in the form of:
which is simplified by the rule:
Here
Hence, by using the formula (1) we get:

Answer:
Option (d) is correct.
6 + 9 + 12 +15 =
Step-by-step explanation:
Consider the given series expansion 6 + 9 + 12 +15.
since we have to write in series form of 3.
We first write each term of given series in term of 3k or 3k+3
6 can be written as 3(2) or 3(1)+3
9 can be written as 3(3) or 3(2)+3
12 can be written as 3(4) or 3(3)+3
15 can be written as 3(5) or 3(4)+3
Thus, we can write the given series as ,
or
Since, we have options to choose.
From the given option (d) matches our result.
So, 6 + 9 + 12 +15 =
The gap consists of the values 6 and 7.
Check out the dot plot below to see what I mean. We have one cluster on the left from 3 to 5. Then another cluster on the right from 8 to 9.
