Answer:
b
Step-by-step explanation:
because it equals -3
Answer:
-3, -6
Step-by-step explanation:
Any number of x that makes the bottom 0 makes the expression undefined.
Factor the polynomial in the denominator:
(x+3)(x+6)
Values of x that makes the expression undefined are -3 and -6

Answer:
Since L.H.S = R.H.S = 0, for both and , y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.
Step-by-step explanation:
To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.
So y" - y = 0 and
Substituting these values of y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So is a solution of the differential equation.
When
Substituting y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So, is a solution of the differential equation.
