Answer 2

⏩Hey mate❤

Factories 4x²-4x-1=0

Solution:-

using Dharacharya formula

x= [-b±√(b²-4ac)]/2a

herd ,

a=4,b= -4,c=-1

so,

x= [-(-4)±√{(-4)²-4×4×-1}]/2×4

x= [4±√(16+16)]/8

x= [4±√32]/8

x= [4±4√2]/8

x=4[1±√2]/8

x= (1±√2)/2

Take +ve and -ve sign

First +ve sign ,

x= (1+√2)/2,

Second take -ve sign

x= (1-√2)/2
