Find the roots of the quadratic equations x2-x/5+1/100=0 |
|
Answer» X2+x/5-1/100 =0100x2-20x+1/100=0.[Both sides multiply by 100]100x2-20x+1=0100x2-10x-10x+1=010x(10x-1)-1(10x-1)=0(10x-1)(10x-1)=0(10x-1)=0 , 10x-1=010x=1, 10x=1X=1/10, x=1/10 Multiplying both sides by 100100x^2-20x+1=0100x^2-10x-10x+1=010x(10x-1)-(10x-1)=0(10x-1)(10x-1)=0X=1/10 |
