Differential Equations Problem

fgiga [73]

Answer:

$y=\frac{t^2e^{2t}}{3}+ce^{2t}$

Step-by-step explanation:

We have given differential equation $\frac{dy}{dt}-2y=t^2e^{2t}$

We know that linear differential equation is given by $\frac{dy}{dt}+Py=Q$

On comparing with standard equation P = -2 and Q= $t^2e^{2t}$

Now integrating factor $IF=e^{-Pdt}$

$IF=e^{-2dt}=e^{-2t}$

Now solution of differential equation is given by

$y\times IF=\int\ IF\times Q\ dt$

$y\times e^{-2t}=\int\ e^{-2t}\times t^2e^{2t}\ dt$

$y\times e^{-2t}=\frac{t^2}{3}+c$

$y=\frac{t^2e^{2t}}{3}+ce^{2t}$

WORTH 50 POINTS NEED HELP ASAP

marishachu [46]

Answer:

-10, -1, 5

Step-by-step explanation:

To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....

x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...

x = -10

x-5=0

then repeat (add 5 to both sides) (and subtract 1 from both sides) ...

x -5 = 0 to x = 5

x + 1 = 0 to x = -1

hope this helps!! tell me if it doesnt make sense and i can help you!! also if it is right can i have brainliest :) no worries though happy to help
