Answer 1

Answer:

1/√2

step by step explanation:2x^2-2√2+1

Formula:-b+-√b^2-4ac/2a

from the equation

a=2

b=-2√2

c=1

= -(-2√2)+-√(-2√2)^2-4*2*1/2*2

=2√2+-√8+8/4

=2√2/4

=1/√2

therefore this has equal roots

For verification :

2x^2-√2x+1=0

2x^2-√2x-√2x+1

(2*√2)x^2-√2x-√2x+1

√2x(√2x-1)-1(√2x-1)

(√2x-1) (√2x-1)

x=1/√2 x=1/√2

hope this helped

all the best

May God bless you
