The product of the given expression is [tex]-12s^2 + 11st - 2t^2[/tex].
The product is a result of one or more multiplications of the given set of numbers or equations.
Given expressions are (-3s +2t) and (4s - t).
We need to find the product of the given expression.
Product = [tex](-3s +2t)(4s - t).[/tex]
Product = [tex]- 12 s^2 + 3st + 8st - 2t^2[/tex]
Product = [tex]-12s^2 + 11st - 2t^2[/tex]
Hence we can conclude that the product of the given expression is [tex]-12s^2 + 11st - 2t^2[/tex].
