Question

Roots of X^2-3x+1 are....... ​

Answer 1

Answer:

x²- 3x + 1

using quadratic formula

D= b² - 4ac

= (-3)² - 4 (1)(1)

= 9- 4

D= 5

x= (-b + √D)/ 2a or (-b - √D)/2a

x = -(-3) + √5/2

x = (3+√5)/2

x = (3-√5)/2

Answer 2

Answer:

(3-√5)/2 and (3+√5)/2

Step-by-step explanation:

we can use the quadratic formula...

x = {-b+-√D}/2a

D is b^2-4ac

In this ques D comes out to be 5

and b is 3 and a is 1...

now just apply the above formula....
