Question

The roots of quadratic equation 5xᒾ -4x +5=0 are real or Not real​

Answer 1

real bcoz D(b²-4ac) is positive

Answer 2

Answer:

let us see that

possibilities are

b^2-4ac<0

b^2-4ac>0

or, b^2-4ac=0

5x^2-4x+5=0

a=5,b=-4,c=5

assuming that equation is equal to zero

-4^2-4×5×5=0

16-4×25=0

16-100=0

-84 not equal to the zero

b^2-4ac<0

then the roots are Not Real
