Q. x2+213x+215=0If x=a and x=b are the solutions to the given equation, what is the value of ab ?Choose 1 answer:(A) −15B −215(C) 215(D) 15
Use Quadratic Equation Formula: We will use the fact that for a quadratic equation of the form ax2+bx+c=0, the product of the roots is given by ac. Here, a=1, b=213, and c=215.
Calculate Product of Roots: We calculate the product of the roots using the formula ac. ab=1215
Simplify Expression: Simplify the expression to find the value of ab.ab=215
