Answer:
+2
Step-by-step explanation:
-(-2)
since: same signs gives the positive sign i.e + and different signs gives negative sign -
-×-2
=+2
we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
Answer: Option D
Explanation:
Arithmetic Progression is the sequence of numbers in which consecutive terms have same or common difference.
common difference d= a2-a1
Option A is incorrect because in last two terms there is not a common difference of 
, 
, 
.
Option B is incorrect because there is not a common difference of 1 in any of the given terms
Option C is incorrect because we do not check common difference in the number of terms that is n we check it for 
.
