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.
