Answer:
cost price (cp)=RS.300
6
Step-by-step explanation:
Pls mark brainliest.
-5x^2 +14x +24
(x-4)(-5x - 6)
FOIL
first : x*-5x = -5x^2
outer : -6x
inner: -4*-5x = 20x
last: -4*-6 = 24
Add them together
-5x^2 -6x+20x +24
If either or , the ODE has the trivial solution , but . So any solution to the ODE that satisfies the initial condition can only exist on the interval .
