What is the product?

(-3s+2t) (4s-t)

12s² + 11st - 2t²

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

- 3s (4s - t) + 2t (4s - t) ← distribute both parenthesis

= - 12s³ + 3st + 8st - 2t² ← collect like terms

= - 12s² + 11st - 2t²

-12s²+11st-2t²

Step-by-step explanation:

(-3s+2t) (4s-t)

=-3s (4s) - 3s (-t) + 2t (4s) + 2t (-t)

=-12s²+3st+8st-2t²

=-12s²+11st-2t²
