Question

find the root of each of the following equation question number 8​

Answer 1

Answer:

$\frac{ \sqrt{2} }{2}$

Step-by-step explanation:

$d \: = {( - 2 \sqrt{2} )}^{2} - 4 \times 2 \times 1 \\ = 8 - 8 \\ = 0 \\ therefore \: roots \: will \: be \: qual \: and \: real \\ x = \frac{ - ( - 2 \sqrt{2} )}{2 \times 2 } \\ x = \frac{2 \sqrt{2} }{4} \\x = \frac{ \sqrt{2} }{2}$

it is in the rationalize form, you can also simplify it further if you can
