  1. Use Quadratic Equation Formula: We will use the fact that for a quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0, the product of the roots is given by ca\frac{c}{a}. Here, a=1a = 1, b=132b = \frac{13}{2}, and c=152c = \frac{15}{2}.
  2. Calculate Product of Roots: We calculate the product of the roots using the formula ca\frac{c}{a}. ab=1521ab = \frac{\frac{15}{2}}{1}
  3. Simplify Expression: Simplify the expression to find the value of abab.ab=152ab = \frac{15}{2}
