Case ll: When roots of AE are same (repeated) Suppose AE f(m)= 0 has two equal roots (m, = m) m MA m, m, m M In this case the solution will be : If three roots

Case ll: When roots of AE are same (repeated) Suppose AE f(m)= 0 has two equal roots (m, = m) m MA m, m, m M In this case the solution will be : If three roots of AE are equal say m, = m, = m,, then y= (C +C,x)e"* + Ce* +.....+Ce"* Y=(C, +C,X + Cx )ex + C,ema +..... +Cn . is the last statement for 3 roots to be equal is true or there is some misprint in the material?
