Squaring both sides :)

OpenStudy (anonymous):

that is the last option do you see any relationship

OpenStudy (hba):

Well i do not recommend it to do that way

OpenStudy (anonymous):

$3x^2+2x+6+2\sqrt{(2x^2+x+5)(x^2+x+1)}=x^2-3x+13$

OpenStudy (hba):

just because of the complications :)

$2x^2+5x-9+2\sqrt{roots}=0$

OpenStudy (hba):

no keep 2underroot on one side and take the rest on one side and then apply squaring both sides again

5 years ago
OpenStudy (hba):

$2\sqrt{roots}=-2x^2-5x+9$

lol i see that adding theroots gives the number outside

$-(p+q)=2\sqrt{pq}$

5 years ago
OpenStudy (anonymous):

$p^2+2pq+q^2=4pq$ $p^2-2pq+q^2=0$

5 years ago
OpenStudy (anonymous):

$(p-q)^2=0$

OpenStudy (anonymous):

p=q

is this correct

5 years ago
OpenStudy (cwrw238):

yes

ithink there is a problem

OpenStudy (anonymous):

i ignored x^2-13x+13 on the right

5 years ago
OpenStudy (cwrw238):

-13x?

OpenStudy (anonymous):

$-2\sqrt{roots}=2x^2+5x-9$ sum of roots dnt give number out side

5 years ago
OpenStudy (anonymous):

no i meant -3x

@hartnn can you see the mistake

its not x=3, i saw your mistake, but i don't have any better method to come up with, thats why i was silent
