Question

if one root of quadratic equations is 3-2√5, find another root​

Answer 1

If one of the roots is 3−25. Then the other root will be 3+25

Thus, sum of roots=6

Product of roots=(3−25)(3+25)=0

                            ⇒9+65−65−20=0

                            ⇒9−20=−11

The equation is : x2−Sx+P=0

x2−6x−11=0
