Question

Write the nature of the roots of quadratic equation 7x^2 -4x +1 =0

Answer 1

Answer:

This way we can solve the problem!!

Answer 2

Step-by-step explanation:

D= B²-4AC

if D> 0 then roots are real

if D< 0 then roots are complex

if D=0 then the roots are equal

in this case , a=7 b=-4 c=1

D=b²-4ac

D=(-4)²-4(7)(1)=16-28=-12

D<0

so the roots are complex
