Answer:

The quadratic equation is x^2 + 7x - 30.

Step-by-step explanation:

sum of roots = 3 + (-10) = 3 - 10 = -7

product of roots = 3 × (-10) = -30

quadratic equation = x^2 - (sum of roots)x + (product of roots)

= x^2 - (-7)x + (-30)

= x^2 + 7x - 30

Answer:the quadratic equation is x^2+7xx-30.

Step-by-step explanation:sum of roots 3+(-10)=3-10=-7

Product of roots 3×(-10) = -30

quadratic equation = x^2 - (sum of roots)x+(product of roots)

=x^2- (-7) x+(-30)

=x^2+7x-30
