Question

Harshit Singh · Answer

Dear Student Given, 100x^2 &ndash; 20x + 1=0 Taking LHS, = 100x^2 &ndash; 10x - 10x + 1 = 10x(10x - 1) -1(10x - 1) = (10x - 1)^2 The roots of this equation, 100x^2 &ndash; 20x + 1=0, are the values of x for which (10x - 1)^2= 0 &there4; (10x - 1) = 0 or (10x - 1) = 0 &rArr;x = 1/10 or x = 1/10 Thanks
