# Find the roots of

Answer :

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

The roots of equation is given by formula i) 2x2 – 7x + 3 = 0

According to the quadratic formula;  The roots are = = = The roots are 3 and ii) 2x2 + x – 4 = 0

According to the quadratic formula; = The roots are = = = The roots are = iii) 4x2 + 4√3x + 3 = 0

According to the quadratic formula; = The roots are = = The roots are iv) 2x2 + x + 4 = 0

According to the quadratic formula; = The roots are = = This is not possible, Hence the roots do not exists.
