Question 370623
{{{x=( 2+sqrt(7))/2}}}
..
you have youself answered the question.As you see above {{{(2+sqrt(7))}}}
is in the numerator
when you simplify each term in the numerator has to be divided by 2
{{{x=((2/2)+(sqrt(7))/2))}}}
={{{x=(1+(sqrt(7))/2)}}}
if you need to simplify further you have to use a calculator to write the answer in decimals.
x= 1+3.228
x= 4.228
..
the same applies for the other root.
