Question

Violet has a TV, a dishwasher and a refrigerator in the back of her truck. The weight of the TV is represented by 2x^2 + 4x and the weight of the dishwasher is x^2 + 3. What polynomial represents the refrigerator if their total weight is 5x^2 + 3x + 9?

Answer 1

well you can add them

Answer 2

all of it ? and combine terms

Answer 3

you are only combining like terms
there should not be any multiplying involved

Answer 4

yep

Answer 5

so the first one is 7x^2 ?

Answer 6

first 1?

Answer 7

in the problem

Answer 8

the 2x and the 5x

Answer 9

o you mean the term

Answer 10

yes

Answer 11

what would be the final answer to this a expression ?

Answer 12

wait
you have the
TV
then you have the
dishwasher

Answer 13

is this the answer 7x^2+4x+12

Answer 14

what ?

Answer 15

total weight = dishwasher + tv + refrigerator
^
unknown (polynomial)

Answer 16

what did you get when you added them ?

Answer 17

if their total weight is 5x^2 + 3x + 9

weight of the TV is represented by 2x^2 + 4x
weight of the dishwasher is x^2 + 3

What polynomial represents the refrigerator

how this would look like

total weight = dishwasher + tv + refrigerator (unknown variable x)

solve like a regular equation its just with polynomials
