Find the roots of the following quadratic equations by factorisation: 100x ^2 – 20x + 1 = 0
Dear StudentGiven, 100x^2 – 20x + 1=0Taking LHS, = 100x^2 – 10x - 10x + 1= 10x(10x - 1) -1(10x - 1)= (10x - 1)^2The roots of this equation,100x^2 – 20x + 1=0,are the values of x for which (10x - 1)^2= 0∴ (10x - 1) = 0or (10x - 1) = 0⇒x = 1/10 or x = 1/10Thanks
