Question

For what value of quadratic equation and x square - 3 x + 1 is equal to zero has equal roots

Answer 1

Answer:

Step-by-step explanation:

x^2-3x+1=0 (:D=0)

For real roots we have, (D=b^2-4ac)

a=1,b=-3 and c=1

D=(-3)^2-4×1×1

=9-4

=5

hence if D>0 then then the roots are unequal and irrational
