Answer:
Sum is -6
Product is 7
Step-by-step explanation:
As we know the formula
x² + (α+β)x + αβ
Here α,β are the roots of the equation
With the above formula we can know the sum and the product of the roots without knowing them
Hope this helps uh...!!!!

can you explain more about it
s surely
like what do you want to know
x² + (α+ β)x + αβ <--- my math teacher said me this short cut
for the same thing which u asked for the product and the sum
but here we don't know alfa and beta how will u use it
s but this is the shortcut right without knowing the α and β we can do that - like they have given the coefficient of x and the constant term as per the formula the coeffiecient of x and the constant term ar the sum and product right
plz thank me
