If the lines x+y= a and x-y= b touch the curve y=x^2-3 x+2 at the points where the curve intersects the x -axis, then a/b is equal to \ \ \ \.
If the lines $\displaystyle x+y=\mathrm{a}$ and $\displaystyle x-y=\mathrm{b}$ touch the curve $\displaystyle y=x^2-3 x+2$ at the points where the curve intersects the $\displaystyle x$-axis, then $\displaystyle \frac{\mathrm{a}}{\mathrm{b}}$ is equal to \_\_\_\_.
