Detailed Solution

x22ax+(a2b2)=0

x22ax+a2b2=0

(xa)2b2=0

(xa+b)(xab)=0

x=ab(or)x=a+b

(or)

Given quadratic equation is x22ax+(a2b2)=0

coefficientofx2×constant

=1×(a2b2)

Now (a2b2)=((ab))×((a+b))

Sum =a+bab

=2a

=coefficientofx

x22ax+(a2b2)=0

x2(ab)x(a+b)x+(ab)(a+b)=0

x[x(ab)](a+b)[x(ab)]=0

[x(ab)][x(a+b)]=0

x(ab)=0 or x(a+b)=0

x=(ab) or x=(a+b)
