Super difficult math problems in Volume 2 of junior high school Given m ^ 2 + 2m-1 = 0, find one of m ^ 2 + m ^ 2

∵ M & # 178; + 2m-1 = 0, ∵ m ≠ 0, divide the two sides of the equation by m to get m + 2-1 / M = 0, or M-1 / M = - 2,
The square of the two sides is M & # 178; - 2 + 1 / M & # 178; = 4, | M & # 178; + 1 / M & # 178; = 6
