Question

The roots of the equation ax'+bx+c=0, ax0 are real and
unequalit b4-ac is
a > 0
b) <0 c) = 0
d) none of the above.​

Answer 1

Required Answer :-

if the roots of given quadratic equations are real and unequal then the value of b^2-4ac is greater than zero (b^2-4ac >0)

extra knowledge :-

if roots of a quadratic equations are real and equal then the value of b^2-4ac is equal to 0 (b^2-4ac=0)

if roots of the quadratic equations are not real then the value of b^2-4ac is smaller than 0 (b^2-4ac < 0)

Final Answer :-

roots of quadratic equation ax^2+bx+c=0, if roots are real and unequal then value of b^2-4ac > 0

Therefore option A is correct✅️✅️
