Question

if one zero of tha polynomial( x square -4x+1 )is (2+√3). write the other zero.

Answer 1

Hii friend,

P(X) = X²-4X+1

here,

A = 1 , B = -4 and C= 1


One zero = 2+✓3

Let Alpha = 2+✓3

Sum of zeros = Alpha + Beta = -B/A

2+✓3 + Beta = -(-4)/1

2+✓3 + Beta = 4/1

Beta = 4-2-✓3

Beta = 2-✓3



HOPE IT WILL HELP YOU..... :-)
