Q12 of 293 Page 460

Find the roots of each of the following equations, if they exist, by applying the quadratic formula:

2x2 + 6√3x – 60 = 0

Given:

Comparing with standard quadratic equation ax2 + bx + c = 0



Discriminant D = b2 – 4ac


=


= 180 + 480 = 588 > 0


Hence the roots of equation are real.



Roots are given by





Hence the roots of equation are
