Question

solve the following x^2-4x+2=0​

Answer 1

Step-by-step explanation:

x² - 4x + 2 = 0

Using discrimant formula,

x = (4+- root(4²-4×2))/2

= (4+-2root2)/2 = 2+-root2

Answer 2

Answer: 1 , 2

Step-by-step explanation:

x^2- 4x+2=0

or, x^2 - (2+2)x + 2=0

or, x^2- 2x-2x+2=0

or, x(x-2) -1(x-2) =0

or, (x-2) (x-1) =0

Either,            OR,

x-2=0            X-1=0

X=2              x=1

    Therefore x= 1 , 2
