Let me ask you a question that you have answered before. Is it possible that the equation (2M2 + M-3) x ^ (M + 1) + 5x = 13 of X is a quadratic equation of one variable? The degree on X is m + 1 one (2m²+m-3)x^(m+1)+5x=13 If it is a quadratic equation of one variable, two conditions should be satisfied 1）m+1=2,m=1 2)2m²+m-3≠0 When m = 1, the above formula = 2 + 1-3 = 0, which does not meet the requirements So it can't be a quadratic equation of one variable two It's similar to the question M-1 = 2, then M = 3 Substituting M = 3 into 2m & # 178; + M-3, we get: 2m²+m-3=2×9+3-3=18≠0 So this could be a quadratic equation of one variable How does m + 1 become M-1 = 2, then M = 3 Substituting M = 3 into 2m & # 178; + M-3, we get: 2m²+m-3=2×9+3-3=18≠0 So this could be a quadratic equation of one variable

Obviously, the answer is not the same question
(1) Can the equation (2M2 + M-3) x ^ (M + 1) + 5x = 13 be a quadratic equation with one variable?
(2) Can the equation (2M2 + M-3) x ^ (m-1) + 5x = 13 be a quadratic equation with one variable?
The number of times on X is m + 1
If it is a quadratic equation of one variable, two conditions should be satisfied
（1）m+1=2,m=1
（2)2m²+m-3≠0
When m = 1, the above formula = 2 + 1-3 = 0, which does not meet the requirements
So (2M2 + M-3) x ^ (M + 1) + 5x = 13 cannot be a quadratic equation with one variable
If M-1 = 2, then M = 3
Substituting M = 3 into 2m & # 178; + M-3, we get:
2m²+m-3=2×9+3-3=18≠0
So (2M2 + M-3) x ^ (m-1) + 5x = 13 may be a quadratic equation with one variable
