Question

Can someone check my work please? Diffy Q's

Answer 1

This isn't adding up to equal the other equation and I"m not sure what I'm doing wrong

Answer 2

step 5\[\frac{ 1 }{ 2 }Bx-Ax=-8x,A=5\]\[\frac{ 1 }{ 2 }Bx-2*5*x=-8x,\]
\[\frac{ 1 }{ 2 }Bx=-8x+10x=2x,B=4\]

Answer 3

you are not supposed to find by complementary solution and particular integral

Answer 4

I assume you follow sshayer's post?
\[ \frac{B}{2} - 2 \cdot 5 = -8\]
solve for B. You don't get -36

Answer 5

Sorry everyone! It never showed me a notification. I got B = 4 and C = -10. I don't understand what @sshayer's second comment means

Answer 6

you are doing good.
if the question is solve above differential eq.
then you have to find general solution and particular integral.
