Answer:
Therefore the auxiliary solution is
Therefore are linearly independent
Step-by-step explanation:
Given, the differential equation is
y"-y'-20 y=0
Let be the solution of the above differential equation.
y'= and
Then the above differential equation becomes
If two roots of m are real and distinct then the auxiliary solution is
[where a and b are two roots of m]
Therefore the auxiliary solution is
Wronskian
≠0
Therefore are linearly independent.[ ∵W≠0]
well, -12+7 is 5 times (23-7=16) so that answer is 80 and 6-(-5*4=-20) so that is also 16
