1. Problem in Latex
2. Mathematica input
3. Maple input

\[ y''(x)=0 \] ✓ Mathematica : cpu = 0.00409005 (sec), leaf count = 12

\[\left \{\left \{y(x)\to c_2 x+c_1\right \}\right \}\]

✓ Maple : cpu = 0.022 (sec), leaf count = 9

\[ \left \{ y \left ( x \right ) ={\it \_C1}\,x+{\it \_C2} \right \} \]

Hand solution

\[ y^{\prime \prime }=0 \]

Integration twice gives

\[ y\left ( x\right ) =c_{1}x+c_{2}\]
