(-3t^2+4t-7)(-2t)
color(white)("XXXX")color(white)("XXXX")=6t^3-8t^2+14t

Explanation:

The Distributive Property (of Multiplication over Addition) tells us:
color(white)("XXXX")(a+b+c) xx (d) = ad +bd+cd

So (-3t^2+4t-7)(-2t)
color(white)("XXXX")= (-3t^2)*(-2t)+(4t)*(-2t)-(7)*(-2t)

color(white)("XXXX")=6t^3-8t^2+14t
