Answer 1

Answer:

For solving a quadratic equation

x=-b+/-√b^2-4ac

---------------------

2a

B^2-4ac is also called discriminant of the equation.

Answer 2

Step-by-step explanation:

the quadratic eq. will be

ax^2+bx +c =0

here a,b,c are constants

roots of quadratic eq.is found by

$x = \frac{ - b + \ - \sqrt{ {b}^{2} - 4ac } }{2a}$

here

$d = \sqrt{ {b}^{2} - 4ac}$

is called determinant and if d=o the roots are rea l and equall

d=+ve ,the roots are real

d=-ve ,the roots are imaginary
