what is the area of the smaller rectangle you can leave the area in factored form if you want

OpenStudy (gabylovesyou):

what do i have to do ? x * x + 2 ?

jimthompson5910 (jim_thompson5910):

actually x * (x+2) and you can leave it factored like that for now

jimthompson5910 (jim_thompson5910):

how about the larger rectangle

OpenStudy (gabylovesyou):

2x * x^2 + 5x + 6 ?

jimthompson5910 (jim_thompson5910):

you need parenthesis, so it's 2x(x^2 + 5x + 6)

jimthompson5910 (jim_thompson5910):

now factor x^2 + 5x + 6

OpenStudy (gabylovesyou):

(x + 2) (x + 3)

jimthompson5910 (jim_thompson5910):

When you divide the smaller area by the larger, you get \[\large \frac{x(x+2)}{2x(x^2+5x+6)}\] which becomes \[\large \frac{x(x+2)}{2x(x+2)(x+3)}\] after you factor

jimthompson5910 (jim_thompson5910):

what cancels?

OpenStudy (gabylovesyou):

(x + 2)

jimthompson5910 (jim_thompson5910):

what else

OpenStudy (gabylovesyou):

the X ? lol

jimthompson5910 (jim_thompson5910):

so that means \[\large \frac{x(x+2)}{2x(x+2)(x+3)}\] turns into \[\large \frac{1}{2(x+3)}\]

jimthompson5910 (jim_thompson5910):

after you do all the cancellations

OpenStudy (gabylovesyou):

got it thank you! :p
