# Find the roots of the quadratic equations given in Q.1 above by applying the quadratic formula.

For a quadratic equation: ax2 + bx + c = 0,

The roots of equation is given by formula

i) 2x2 – 7x + 3 = 0

The roots are =

=

=

The roots are 3 and

ii) 2x2 + x – 4 = 0

=

The roots are =

= =

The roots are =

iii) 4x2 + 4√3x + 3 = 0

=

The roots are =

=

The roots are

iv) 2x2 + x + 4 = 0

=

The roots are =

=

This is not possible, Hence the roots do not exists.
