The indicated function y1(x) is a solution of the given equation. Use reduction of order or this formula, y2 = y1(x) e−∫P(x) dx y12(x) dx , as instructed, to find a second solution y2(x). y'' − 4y' + 4y = 0; y1 = e2x y2 =

Step-by-step explanation:

We have the differential equation  y'' − 4y' + 4y = 0,

so we get that is p(x)=-4.

We use the formula:

We have that:

we calculate:

So, we get that

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
