AS further maths roots of quadratics question

Just a quick question, ive been given a quadratic and using its roots, α\alpha and β\beta, i have to form equation with related roots.

i have to find an equation with integer coefficients whose roots are αβ2\alpha\beta^2 and α2β\alpha^2\beta.

Is the product of αβ2\alpha\beta^2 and α2β\alpha^2\beta
α3β3\alpha^3\beta^3 or do i put it into brackets and expand?

yes it is α3β3\alpha^3\beta^3 I am not sure what you were thinking of doing with brackets

I thought that since i had to multiply them it would make sense to do
(αβ2)(α2β)(\alpha\beta^2)(\alpha^2\beta) and then multiply out the brackets

ok

but that is α3β3\alpha^3\beta^3 so I am still not sure what you were thinking
