    X2+x/5-1/100 =0 100x2-20x+1/100=0.[Both sides multiply by 100] 100x2-20x+1=0 100x2-10x-10x+1=0 10x(10x-1)-1(10x-1)=0 (10x-1)(10x-1)=0 (10x-1)=0 , 10x-1=0 10x=1, 10x=1 X=1/10, x=1/10

    1Thank You

    Multiplying both sides by 100 100x^2-20x+1=0 100x^2-10x-10x+1=0 10x(10x-1)-(10x-1)=0 (10x-1)(10x-1)=0 X=1/10
