Answer:

#3s^2-19s+20#

Explanation:

In simplifying this product we must ensure that each term in the 2nd bracket is multiplied by each term in the 1st bracket.

We can do this as follows.

#(color(red)(3s-4))(s-5)=color(red)(3s)(s-5)color(red)(-4)(s-5)#

multiply out the brackets.

#=3s^2-15s-4s+20=3s^2-19s+20#

which is in standard form.
