Question

what is the nature of roots of the equations x2-4x+1=0​

Answer 1

Answer:

The roots of the given equation will be real and unequal.

Step-by-step explanation:

Answer 2

x2-4x+1=0. by quadratic formula

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

X= -b+-√b2-4ac/2a

X= [-(-4)+-√(-4)square--4(1)(1) ]/2(1)

x=(4+-16-4)/2

x=(4+-10)/2

then,

X=(4+10)/2 and X=(4-10)/2

X=14/2. and X=-6/2

X=7. and X=-3

Two root = 7 and -6
