Question

Form the quadratic equation from the roots given below. i) 2 − √ , 2 +√​

Answer 1

Step-by-step explanation:

Form the quadratic equation from given roots

=-√2 ,+√2

when sign of a number is changed but magnitude is same then,

Solution:-

let x=+-√2

Squaring both sides

(x)^2= (+-√2)^2

x^2= 2

transpose 2 to left side

x^2-2= 0

Hence,the quadratic equation is x^2-2
