Question

without determine the roots, comment upon the nature of the roots of the quadratic equation 7^2-6x+7=0​

Answer 1

Answer:

imaginary roots or the roots are unreal.

Step-by-step explanation:

discriminant = b² - 4ac

here a = 7 b = - 6 c = 7

so b² - 4ac = (-6)² - 4 × 7× 7

= 36 - 196

= - 166< 0

Therefore b² -4ac < 0

The roots are imaginary.
