Question

Write a quadratic equation whose one root is (1-√2)

Answer 1

Step-by-step explanation:

• if one root is
• $1 - \sqrt{2}$
• then the root will be
• $1 + \sqrt{2}$
• let the roots be A,B then a+b=2 and product equal to -1
• as we Know the eq is x square -(A+B)x+AB=0
• so the eq:x square -2x-1=0
