Answer 3

It looks like you have two expressions, and you would like to expand them. Let's expand each expression:

1. $(y+2)(3-a)$

To expand this expression, you can use the distributive property, also known as FOIL (First, Outer, Inner, Last):

First: $y \cdot 3 = 3y$ Outer: $y \cdot (-a) = -ay$ Inner: $2 \cdot 3 = 6$ Last: $2 \cdot (-a) = -2a$

Now, combine these results:

$(y+2)(3-a) = 3y - ay + 6 - 2a$

2. $(x-1)(x-3)$

Again, you can use FOIL to expand this expression:

First: $x \cdot x = x^2$ Outer: $x \cdot (-3) = -3x$ Inner: $(-1) \cdot x = -x$ Last: $(-1) \cdot (-3) = 3$

Combine these results:

$(x-1)(x-3) = x^2 - 3x - x + 3$

Simplify further:

$(x-1)(x-3) = x^2 - 4x + 3$

So, the expanded expressions are:

1. $3y - ay + 6 - 2a$
2. $x^2 - 4x + 3$
