m²-3m -1=0

comparing the given equation with ax²+but+c=0......... general form of the quadratic equation.

therefore a= 1,b=-3 and c=-1

third term= (b/2) ²

= (-3/2) ²

=9/4

m²-3m+9/4-9/4-1=0

(m+3/2) ²-9/4-1=0

(m+3/2) ²-9-4/4=0

(m+3/2) ²=13/4

m+ or - 3/2=√13/2.

therefore, m= √13-3/2

or m= √13+3/2
