Polynomial multiplication and addition (area/per)

Combine like terms by adding

• $12p^{4^{ }}+3$

• $-3p^4+5p^{3\ }+9p^2$

• $-3p^4+5p^{3\ }+2p$

• $3p^4-5p^{3\ }-9p^2$

Subtract the polynomials.

•  $-b^4+6b^2-1$  

•  $-4b^{4^{ }}+1b^2-9$  

•  $-b^4+13b^3-6b^2+1$  

What would you need to do first to solve?

• add like terms

• draw your area model

• subtract like terms

• divide the like terms

Multiply the polynomials

• $12p^2+48p$

• $12p+48p-16$

• $12p^2-48p+21$

What is the area of the rectangle above?

• 5x²

• 25x²-20x

• 45x²

• 20x+25x

find the perimeter of this rectangle (hint: YOU MUST FILL IN THE OTHER SIDES)

• 8y⁶

• 8y⁵

• 6y³+10y²

• 15y⁶

If a rectangle has the length of 8n+3 and the width of 4n-7, what is the AREA of the triangle? ^{(hint: draw your area model!)}

• 32n-21

• 32n²-21

• 32n²-44n-21

• 12n-4

Find the perimeter of the rectangle

• 4x+25

• 4x⁴+5

• 25x

• 4x+10

Area means you ___________ the sides

• add

• subtract

• multiply

• divide

Perimeter means you ___________ the sides up

• add

• subtract

• multiply

• divide
