Find the value of a so that the differential equation y ' − xy − 6x = 0 has a solution of the form y(x) = a + bex2/2 for any con

SVEN [57.7K]

Hello,

$y=a+be^\frac{ x^{2} }{2} \\\\

y'=a'+b*x*e^\frac{ x^{2} }{2} \\\\

y'-xy-6x=0\\\\

a'+b*x*e^\frac{ x^{2} }{2}-b*x*e^\frac{ x^{2} }{2}-ax-6x=0\\\\

a'=x(a+6)\\\\

 \dfrac{a'}{a+6} =x\\\\

ln (a+6)= \dfrac{x^2}{2} +c\\\\

a=k*e^\frac{ x^{2} }{2}-6\\\\

-4(9n + 9) = -12(4n - 6).

WITCHER [35]

Answer:

n = 9

Step-by-step explanation:

Step 1: Write equation

-4(9n + 9) = -12(4n - 6)

Step 2: Solve for n

Distribute: -36n - 36 = -48n + 72

Add 48n to both sides: 12n - 36 = 72

Add 36 to both sides: 12n = 108

Divide both sides by 12: n = 9

Step 3: Check

Plug in n to verify if it's a solution.

-4(9(9) + 9) = -12(4(9) - 6)

-4(81 + 9) = -12(36 - 6)

-4(90) = -12(30)

-360 = -360
