Answer 1

Answer:

you can solve this by following formula

Answer 2

-1,-3

Step-by-step explanation:

By using middle term splitting

$(x^2+3x)+(x+3)\\x(x+3)+1(x+3)\\(x+1)(x+3)\\x=-1,x=-3\\\\\alpha +\beta=\frac{-b}{a}=4\\\alpha\beta=\frac{c}{a}=3\\x^2+(\alpha+\beta)x-\alpha\beta\\x^2+(4)x+3\\x^2+4x+3\\\\Proved$
