1. Warm-Up Review for quiz
Use the order of operations to solve the following and explain using a T-chart
– 2(7 – 25 ÷ 5)3
Evaluate the following expression
Let x = 3 y = (-2) z= (-1)
2) 3x2 + 2y – 5z + xyz

2. Combining like terms with subtraction with no exponents
Example
1) x – 2x
2) 2x + 4x – 3x – 5x
2x + 5x + (-3x) + (-5x)
3) 3xy – 4xy + xy – 7xy
3xy + (-4xy) + xy + (-7xy)
4) 7p + 3p – 4p – 5p
7p + 3p + (-4p) + (-5p)

3. More Combining with exponents
1) x2 + 3x2 – 7x2
x2 + 3x2 + (-7x2)
2) -5x3 – 2x3 + 3x3 – 4x3
-5x3 + (-2x3) + 3x3 + (-4x3)
3) 3x3 – 4x4 – 5x3 – 2x4 + 8x5
3x3 + (-4x4) + (-5x3) + (-2x4) + 8x5
