I will do one only.
(x^2-7x+5)(3x-3)
Just multiply across.
3x times x^2 = 3x^3
3x times -7x = -21x^2
3x times 5 = 15x
=====================
We now do the same thing with -3.
-3 times x^2 = -3x^2
-3 times -7x = 21x
-3 times 5 = -15
=====================
Let's put everything together and simplify.
3x^3 - 21x^2 + 15x - 3x^2 + 21x - 15
3x^3 -24x^2 + 36x - 15...This is your final answer.
