Using formula method to solve the equation MX '- (3m + 2) x + 2m + 2 = 0 (M is not 0)

Using formula method to solve the equation MX '- (3m + 2) x + 2m + 2 = 0 (M is not 0)

If (m-2) x 2; - (m 3) x-2m-1 = 0, M = 2, then - 5x-5 = 0, x = - 1, m ≠ 2, a = m-2, B = - (m 3), C = - 2m-1 △ = B 2; - 4ac = m 2; 6m 9
