Determinants
The solution of $y'-y''=2 x$ is:
A. $y=x^2+2 x+2$B. $y=x^2+2 x+1$C. $y=x+2$D. $y=x^2-2 x+1$
Choose the correct answer from the options given below:
A and B only
B only
C only
A and D only
$y'-y''=2 x$
\( \begin{array}{ll}\mbox{A.} &y=x^2+2 x+2 &y'=2 x+2 &y''=2 & &y'-y''=2 x\\\mbox{B.} &y=x^2+2 x+1 &y'=2 x+2 &y''=2 & &y'-y''=2 x\\\mbox{C.} &y=x+2 &y'=1 &y''=0 & & y'-y''=1\\\mbox{D.} &y=x^2-2 x+1 &y'=2 x-2 &y''=2 & & y'-y''=2 x-4\end{array}\)
so option 1
