Answer:
Step-by-step explanation:
Given vectors are = (1,2,1) , = (2,1,4) and = (4,5,6)
We consider a linear equation
a + b = where a and b are constant.
⇔a(1,2,1) +b (2,1,4) = (4,5,6)
⇔(a,2a,a) + (2b,b,4b) = (4,5,6)
⇔(a+2b,2a+b,a+4b) = (4,5,6)
Therefore a+2b = 4 ,
2a+b= 5 ,
and a+4b = 6
From the above set of equations we get a = 2 and b = 1
Since we get the value of a and b so the vectors are linearly dependent.
