Question

Find the roots of the following quadratic equations by factorisation:100x²-20x+1=0​

Answer 1

Answer:

(10x-1) (10x-1)

Step-by-step explanation:

For factorization of this, you have to think two number such that sum of both this number is 20 and multiplication of both this number is 100.

So, these numbers are 10,10.

Now, 100x^2 - 20x + 1

= 100x^2 - 10x - 10x + 1

From first two terms take 10x common and from next two terms take -1 common, so

= 10x( 10X -1) -1 (10x - 1)

= (10x-1) (10x-1)
