Alfa + beta = 2
Alfa*beta = -15
Quadratic polynomial formula
x^2 - (Alfa+beta)x + (Alfa*beta)
x^2 - 2x -15
Thus the required quadratic polynomial is x^2 - 2x -15
Alfa*beta = -15
Quadratic polynomial formula
x^2 - (Alfa+beta)x + (Alfa*beta)
x^2 - 2x -15
Thus the required quadratic polynomial is x^2 - 2x -15
