Question

Find the roots of quadratic eqn by Factorisation method. 100x2 -20x +1=0​

Answer 1

Answer:

comparing the given equation by ax^2+bx+c we get,

a = 100

b = -20

c = 1

∆ = b^2-4ac

= 400 - 400

= 0

x,y = -b√∆/2a

= 20/200

= 1/10

(this equation has only one solution because it's delta is zero and equation whose delta is zero has only one real root)
