    Answer:

    x^2 + 3x – 10

    Step-by-step explanation:

    alpha = 2 , beta = -5

    sum of zeroes = alpha + beta    

                            = 2 + (-5)

                            = 2-5

                            = -3

    product of zeroes = alpha*beta

                                =  2*(-5)

                                 = -10  

    substituting the values in the formula [x^2 – ( alpha + beta )x + alpha*beta ] we get

    [ x^2 – ( -3)x + (-10)]

    x^2 +3x – 10
