Sum of the zeros=2+√3 + 2-√3,
=2+2=4,
product of the zeros=(2+√3)(2-√3),
=2²-√3²
=4-3=1,
therefore
quadratic equation will be
x²-(sum of zeros)x+product of zeros=0,
x²-4x+1=0
=2+2=4,
product of the zeros=(2+√3)(2-√3),
=2²-√3²
=4-3=1,
therefore
quadratic equation will be
x²-(sum of zeros)x+product of zeros=0,
x²-4x+1=0
