The document discusses combining like terms in algebraic expressions. It shows that when you have Ax + Bx, you can combine the like terms to get (A + B)x. As an example, it shows 5x - 3x can be combined to (5 - 3)x, which equals 2x.

1. Combining like terms
Ax + Bx =

2. Combining like terms
Ax + Bx = (A + B) x

3. Combining like terms
Ax + Bx = (A + B) x
5x−3x =

4. Combining like terms
Ax + Bx = (A + B) x
5x−3x = (5−3) x

5. Combining like terms
Ax + Bx = (A + B) x
5x−3x = (5−3) x
= (2) x

6. Combining like terms
Ax + Bx = (A + B) x
5x−3x = (5−3) x
= (2) x
= 2x
