Question

If one roots of quadratic equation ax2+bx+c=0 are equal in magnitude

Answer 1

We know that when discriminate is equals to 0 .Then,

Zeros of the quadratic equation

$= \frac{ - (co - efficient \: of \: x)}{2 \times \: co - effient \: of \: {x}^{2} } \\ \\ = > \frac{ - b}{2a}$

Answer 2

Answer:

We know that when discriminate is equals to 0 .Then,

Zeros of the quadratic equation

-co-efficient of x/ 2×co-efficient of x^2

= -b/2a
