Quadratic equation with roots 1/3 and -7/2 is:

Step-by-step explanation:

Roots of the equation are 1/3 and -7/2

Quadratic equation is of the form:

Now  Sum of roots =

Sum of roots =

∴ b = 19 and a = 6

Product of roots = c/a

Product of the roots =

∴ a = 6, b = 19  and c = -7

So the quadratic equation with roots 1/3 and -7/2 is:
