Answer:

Step-by-step explanation:
y′′ + 4y′ − 21y = 0
The auxiliary equation is given by
m² + 4m - 21 = 0
We solve this using the quadratic formula. So

So, the solution of the equation is

where m₁ = 3 and m₂ = -7.
So,

Also,

Since y(1) = 1 and y'(1) = 0, we substitute them into the equations above. So,


Substituting A into (1) above, we have

Substituting B into A, we have

Substituting A and B into y, we have

So the solution to the differential equation is

99 R 4
499 divided by 5 = 99 R4
2x + 2
2(x+1)
where’s the value of X and the given of g(x)=???
16 1/5 seconds = 16.2 seconds
19.8 - 16.2 = 3.6
