Answer 2

Answer:

we know that alpha+beta=-b÷a,. so, let alpha-beta=1--------equation 1st then,let alpha+beta=-b÷a------equation 2nd then,eliminate both the equations we get beta=2 and when we put the value of beta into equation 1st it gives us alpha=3 now,in the product of zeroes{alpha×beta=c÷a} we put the values of alpha and beta.so,the equation is 3×2=k÷1 so, tge value of k is 6
