Question

x square minus three x plus one =0

Answer 1

x² - 3x + 1 = 0

By Quadratic equation,

a = 1
b = 3
c = 1

Then,

Discrimunant = b² - 4ac

D = 3² - 4(1×1)

D = 9-4

D = 5

Now,

Quadratic equation = [-b±√d]/(2a)

=> [-3±√5]/(2×1)


Roots are :-

• (-3+√5)/2 = x

OR.


• (-3 - √5)/2 =x

I hope this will help you
