The two roots [tex]a +\sqrt{b}[/tex] and [tex]a -\sqrt{b}[/tex] are called conjugate radicals
Conjugate of a radical
The conjugate of a radical is the value which when multiplied with the radical expression clears the radical. Conjugates have the same numbers but the opposite sign in the middle.
The given roots are
[tex]a +\sqrt{b}[/tex] and [tex]a -\sqrt{b}[/tex]
They have the same numbers but opposite signs in the middle.
Hence, the two roots [tex]a +\sqrt{b}[/tex] and [tex]a -\sqrt{b}[/tex] are called conjugate radicals
