Answer:
PLZ MARK AS BRAINLIEST !
Step-by-step explanation:
A quadratic equation, ax2 + bx + c = 0; a ≠ 0 will have two distinct real roots if its discriminant, D = b2 - 4ac > 0.
(i) FOR EXAMPLE - Given equation is x2 – 3x + 4 = 0
On comparing with standard equation we have,
a = 1, b = –3 and c = 4
Now, D = b2 – 4ac = (–3)2 –4(1) (4) = 9 – 16 = – 7< 0
Hence, the equation x2 –3x + 4 = 0 has no real roots.
