Under what condition there will be no real roots of the quadratic equation ax2+bx+c=0

Question

Under what condition there will be no real roots of the quadratic equation ax²+bx+c=0

(a) b² - 4ac = 0

(b) b² - 4ac > 0

(c) b² - 4ac < 0

(d) b² - 4ac = 1

Answer 1

Correct option (c) b² - 4ac < 0

If b2 – 4ac < 0 then the quadratic function has no real roots.
