Step-by-step explanation:
3x+2y=2------------1
-3x+5y=5-----------2
adding 1 and 2 we get
7y=7
y=1
and from (1),we get
3x+2×1=2
3x=0
x=0 is the required value of x.
The second term of the expansion is .
Solution:
Given expression:
To find the second term of the expansion.
Using Binomial theorem,
Here, a = a and b = –b
Substitute i = 0, we get
Substitute i = 1, we get
Substitute i = 2, we get
Substitute i = 3, we get
Substitute i = 4, we get
Therefore,
Hence the second term of the expansion is .
