Answer:
1/10, 1/10 are two roots of given Quadratic equation.
Explanation:
Given quadratic equation:
100x²-20x+1=0
=> (10x)² -2*(10x)+1² = 0
=> (10x-1)² = 0
/* By algebraic identity
a²-2ab+b² = (a-b)² */
=> 10x-1 = 0 or 10x-1 = 0
=> 10x = 1 or 10x = 1
=> x = 1/10 or x = 1/10
[ equal roots ]
Therefore,
1/10, 1/10 are two roots of given Quadratic equation.
