Question

if root 2 + 1 is a root of quadratic equation with rational coefficients write its other root

Answer 1

Answer:

Step-by-step explanations:

1+ under root 2 is a zero of p(x)

Then sum of zeroes= -b/a (rational) ( given)

Also product of zeroes = c/a (rational)

Since irrational roots occur in conjugate pair

Therefore the other root is 1- under root 2
