2.2 strat
Warm UP!!!!
find the sum
2 2(3 4 5) (5 3 4)x x x x
Remember Like terms: Have the same variable and exponent
14x2 12x2 7g 81g
5c 45c 7w3 34w3
Match the like terms
• 18x• 15y2
• 2m• 7z3
• 9w4
• 17y2
• 3m• 5z4
• 7w4
• 45z3
• 16x
You can only add/ subtract like terms!!!14x + 5x = 19x
12y – 4y = 8y
4c + 5y = NO!!
Rules for Exponents:When you add/subtract like terms you keep the exponent the same
3x2 + 5x2 = 8x2
14x2 – 7x2 = 7x2
Rules for exponents:When you multiply terms you multiply the
coefficients and ADD the exponents.
4x2 ( 8x3 + 5x2) = 32x5 + 20x4
2x( 15x2 + 5x + 4) = 30x3 + 10x2 + 8x
Find the product.
2x2(3x2 -5x + 1)
3x2 -5x +1
x2
Find the product. 3x2( 7x2 +2x +5)
7x2 +2x +5
3x2
You Try!!! Find the product
4x5(3x3 -2x2 – 8x +5)
find the product: (w+2)( w2 +8w + 1)
w2 +8w +1
w
+2
Find the product: (5x – 2)( 10x2 –x +5)
10x2 -x +5
5x
-2
Find the product: ( 3x + 3) ( 2x – 5)
2x -5
3x
+3
Find the product: ( 6a – 4)( 5a – 1)
5a -1 6a -4
Simplify the expression:a(3a + 1) + (a + 1)(a + 2)
3a +1 a
a +2 a +1
Combined like terms …..
You try!! Simplify the expression
2p(p3 +2p) + ( p -3)(p+5)
Write a polynomial for the area of the model.
