Question

WHAT IS THE QUADRATIC EQUATION WHOSE ZEROS ARE 2+√3

Answer 1

Answer:

The zeros are 2+ 3and 2− 3

Let the quadratic polynomial be (x−r 1)(x−r 2 ) where r 1

and r 2are the zeros of the polynomial.

Thus the polynomial is

[x−(2+ 3)][x−(2− 3 )]

=(x−2− 3)(x−2+ 3 )

=(x 2 −2x+ 3x−2x+4−23−3x+2 3−3)

=x 2 −4x+1
