On the equation x & # 178; + KX + 4K & # 178; = K-3 = 0 of X, there are two unequal real roots, one of which is 0 If there is m, the absolute value of the difference between the two is 1

On the equation x & # 178; + KX + 4K & # 178; = K-3 = 0 of X, there are two unequal real roots, one of which is 0 If there is m, the absolute value of the difference between the two is 1

The equation x & # 178; + KX + 4K & # 178; - K-3 = 0 of X has two unequal real roots, one of which is 0, and then has 4K & # 178; + K + 3 = 0k1 = - 1 (not suitable for the problem, omit) K2 = - 3 / 4, and substitute K2 = - 3 / 4 into X & # 178; + (K-M) x - (M + K & # 178;) + 5k-2 = 0. After simplification, we use Weida's theorem to find X1 + x2 and x1x2
