Answer 1

This is the answer hope it will be helpful to u so enjoy

Answer 2

Answer:

x²+9x+20

Step-by-step explanation:

α= -4,. β= -5

Now,. α+β= (-4)+(-5) = -9

αβ= (-4)×(-5) = 20

We know that any quadratic equation is in the form,

x²-(α+β)x+(αβ)

Hence, required polynomial = x²-(-9)x+20 = x²+9x+20
