Question

`{x}^(2) -`which could be the missing term in the expression if a factor of the expression is x-2ya) 2xyb) -2yc)
`{4y}^(2)`d)4y

Answer 1

This is a difference of two squares.

If one factor is

`x+2y`

An the other is

`x-2y`

We have that the expression is:

`(x+2y)\cdot(x-2y)=x^2-4y^2`

So the missing term is 4y², option c
