What is the product?
zepelin [54]

Answer:

Option D

Step-by-step explanation:

We need the product of:

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

We can use the distributive property:

(a + b)*(c + d) = a*c +b*c + a*d + b*d

Applying to our case:

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

(-3s + 2t)*(4s - t) = -12(s^2) + 3st + 8ts - 2(t^2)

(-3s + 2t)*(4s - t) = -12(s^2) + 11ts - 2(t^2)

So, the correct is option D negative 12 s squared + 11 s t minus 2 t squared
