I think you use the idea that the roots must come in conjugate pairs if you do not want irrational coefficients

OpenStudy (anonymous):

just find their respective conjugates as irrational roots always occur in conjugate pairs for a+sqrt(b) the conjugate is of the form a- sqrt(b)

OpenStudy (anonymous):

this is not going to be as hard as it looks

OpenStudy (anonymous):

if the roots are \(7+\sqrt{3}\) and \(7-\sqrt{3}\) we can reconstruct the quadratic almost in your head it will be \[x^2-14x+49-3\] or \[x^2-14x+46\]

OpenStudy (anonymous):

ooh i see you just need the other roots! it is the conjugate of each one

OpenStudy (anonymous):

the conjugate of \(a+\sqrt{b}\) is \(a-\sqrt{b}\)

OpenStudy (anonymous):

pick those

lol first medal IN my Life YEAH ^-^
