Question

if one root of the quadratic equation X square - 4 x + 1 is equal to zero is 2 + root 3 then the other root is​

Answer 1

is the root of the given quadratic equation. Thus,

(1)

2

+p(1)+3=0

p+4=0

p=−4

Thus, the equation becomes x

2

−4x+3=0

x

2

−x−3x+3=0

x(x−1)−3(x−1)=0

(x−1)(x−3)=0

x=1,3

Hence,
