Please solve it because this homework will be collected tomorrow
dont take a long if you answer it please 100x

Answer 1

X² + (m+1)x +2m-1 -----> a=1, b= m+1, c=2m-1
D=0 --> b²-4ac =0
(m+1)² -4(1)(2m-1) = 0
(m²+2m+1) - 4(2m-1) = 0
(m²+2m+1) -8m + 4 =0
m²+2m+1-8m+4=0
m²-6m+5=0
(m-1)(m-5) = 0
m=1 atau m=5
