Question

e
by using
using quadratic formula x²-3x + 1=0​

Answer 1

Answer:

2.618 or 0.382

Step-by-step explanation:

x² - 3x + 1 = 0

a = 1, b = -3, c = 1

Quadratic formula = (-b) ± √b²-4ac

-----------------------

2a

= -(-3) ± √(-3)²-4*1*1

-----------------------------

2*1

= 3 ± √9-4

----------------

2

= 3 ± √5

------------

2

= 3 ± 2.236

-----------------

2

3 + 2.236 or 3 - 2.236

---------------- ----------------

2 2

5.236 or 0.764

---------- -----------

2 2

= 2.618 or 0.382

x = 2.618 or 0.382

Note : I put the value of √5 in this answer if you don't want that, then the answer will be 3 + √5 / 2 or 3 - √5 / 2

Hope it helps..❤️
