Answer 1

\[(a-b)^2 = a^2 -2ab+b^2\]
So try it with \[(5y-3)^2\]

Answer 2

Ok so first you have to set it up

\[(5y+-3)(5y+-3)\]

Then let's put it in expanded form

\[(5y)(5y)+(5y)(-3)+(-3)(5y)+(-3)(-3)\]

That will then come out to

\[25y^2-15y-15y+9\]

Which can be simplified to

\[25y^2-30y+9\]

Answer 3

so its D?

Answer 4
