Answer:
Option A is correct.
Step-by-step explanation:
We are given:
We need to find the value of a.
The LCM of (2+i) and (3+i) is (2+i)(3+i)
Now rationalize the denominator by multiplying by 5-5i/5-5i
We are given
Now after solving we have:
So value of a = 1/10 and value of b = -1/10
So, Option A is correct.
It's easier to explain a situation if there's bias or if you feel a certain way about one topic but not the other
Lets say x is the smaller number and y is the bigger number.
x + y = 436
x + 134 = y
We can substitute the second equation into the first (substitute x + 134 in for y)
x + (x+134) = 436
2x + 134 = 436
2x = 302
x = 151
We can now plug this back into either formula (i use the second)
151 + 134 = b
b = 285
The 2 numbers are 151 and 285
