1. Given the quadratic equation in $x$, $x^{2}-(2 m+1) x$ $+m+2=0$ has two integer solutions, find the value of $m$ and the two integer solutions of the equation.
1. Answer: $m=2$, solutions 1, 4; $m=-2$, solutions -3, 0. Hint: Use the relationship between roots and coefficients, then eliminate $m$.
